Buffer

Returns value at the provided index.

Returns a trimmed copy of an underlying array.

Wraps accessible internal state as a Slice without making any copy.

Shift current content to the right starting from index at the insertLength distance, and copies array chunk into the gap.

• Sets topIndex to be at least at the end of the new chunk of values.

Shift current content to the right starting from index at the slice.length distance, and copies slice into the gap.

• Sets topIndex to be at least at the end of the new chunk of values.

Moves values in [fromIndex, toIndex) to the left at a distance, to become [fromIndex - distance, toIndex - distance), and moves right any existing values in [fromIndex - distance, fromIndex) to become [toIndex, toIndex + distance).

• Ignores negative distance.
• Does nothing if fromIndex > topIndex.
• Moves topIndex if affected.

Moves values in [fromIndex, toIndex) to the right at a distance, to become [fromIndex + distance, toIndex + distance), and moves left any existing values in [toIndex, toIndex + distance) to become [fromIndex, fromIndex + distance).

• Ignores negative distance.
• Does nothing if fromIndex > topIndex.
• Moves topIndex if affected.

Attempts to optimize buffer storage, if needed.

Replaces current values in the range [index, index + replaceLength) with values of the array range [sourceIndex, sourceIndex + replaceLength).

Replaces current values in the range [index, index + slice.length) with values of the slice.

Moves values in [index, length) left to [index-distance, length - distance). Effectively removes range (index-distance, index].

• Ignores negative distance.
• Moves topIndex if affected.

Moves values in [index, length) right to [index+distance, length + distance). Effectively creates a new range [index, index+distance).

• Ignores negative distance.
• Does not clear existing values inside [index, index+distance).
• Moves topIndex if affected.

Takes range and returns a Slice.

Swap values in range [first, first + swapLength) with values in range [second, second + swapLength)

• Does nothing if any index falls outside [0,length) or if indexes are equal.
• if [first, first + swapLength) overlaps with [second, second + swapLength) then the later overwrites the former.

Returns a trimmed copy of an underlying array.

Updates value at the provided index.

Appends value at the end of the buffer and advances topIndex.

Appends values from the given iterator at the end of the buffer and advances topIndex.

Appends number of values from the given iterator at the end of the buffer and advances topIndex.

Appends values from the given iterable at the end of the buffer and advances topIndex.

Appends values from the given sequence at the end of the buffer and advances topIndex.

Appends values from the given slice at the end of the buffer and advances topIndex.

Returns true if buffer contains given value.

Returns true if buffer contains value fulfilling the predicate.

Moves topIndex value right by the distance.

Returns Some value at the index, or None if index outside of range.

Returns value at the topIndex.

Returns Some value at the topIndex or None if empty buffer.

Returns this buffer without a first element.

Shifts content in [index, length) one step to the right and updates value at index.

Inserts iterated values into the gap made by shiftjng buffer right, starting from the index.

• Sets topIndex to be at least at the end of the new chunk of values.

Shift current content to the right starting from indexat the min(iterator.length, insertLength) distance, and inserts iterated values into the gap.

• Sets topIndex to be at least at the end of the new chunk of values.

Inserts iterated values, in the reverse order, into the gap made by shiftjng buffer right, starting from the index.

• Sets topIndex to be at least at the end of the new chunk of values.

Shift current content to the right starting from indexat the min(iterator.length, insertLength) distance, and inserts iterated values into the gap in the reverse order.

• Sets topIndex to be at least at the end of the new chunk of values.

Shift current content to the right starting from indexat the insertLength distance, iterates over the source indexes and copies values into the gap.

• Sets topIndex to be at least at the end of the new chunk of values.

Is the accessible part of the buffer empty?

Returns an iterator over actual buffer values, starting from the zero index up.

Returns value at the zero index.

Returns Some value at the zero index, or None if empty buffer.

Length of the accessible part of the buffer.

Iterable representing lazily mapped values of this buffer at the time of access.

Updates in-place all values in the range [0,length) using the function.

Updates value at the provided index using the function. Index must fall within range [0,length).

Updates all values in the range [0,length) using the function.

Updates all accepted values in the range [0,length) using the function.

Updates values in the range [startIndex,toIndex)^^[0,length) using the function. One of {startIndex,toIndex} must fall within range [0,length).

Updates values in the range [startIndex,toIndex)^^[0,length) using the function. One of {startIndex,toIndex} must fall within range [0,length).

Is the accessible part of the buffer non empty?

Returns value at the topIndex.

Returns value at the topIndex - offset.

Returns value at the topIndex - offset.

Returns value at the topIndex, and moves topIndex back.

Appends value to the topIndex. Same as append

Removes value at index and shifts content in [index+1, length) to the left.

Removes values in the range [fromIndex, toIndex) and shifts content in [toIndex, length) to the left.

Removes values matching the predicate.

Replaces current values in the range [index, index + replaceLength) with values returned by the function when iterating argument in the range [sourceIndex, sourceIndex + replaceLength).

Resets buffer, sets topIndex to -1.

• Does not clear existing values.

Returns a reverse iterator over actual buffer values, starting from the topIndex down.
