Attributes
Simplify space such that a space equal to Empty becomes Empty
Simplify space such that a space equal to Empty becomes Empty
Attributes
Whether the extractor covers the given type
Whether the extractor covers the given type
Attributes
Decompose a type into subspaces -- assume the type can be decomposed
Decompose a type into subspaces -- assume the type can be decomposed
Attributes
Remove a space if it's a subspace of remaining spaces
Remove a space if it's a subspace of remaining spaces
Note: dedup will return the same result if the sequence >= 10
Attributes
Display spaces. Used for printing uncovered spaces in the in-exhaustive error message.

Attributes
Intersection of two spaces
Intersection of two spaces
Attributes
Return a space containing the values of both types.
Return a space containing the values of both types.
The types should be atomic (non-decomposable) and unrelated (neither should be a subtype of the other).
Attributes
Is the unapply or unapplySeq irrefutable?

-
The unapply function tree
Attributes
Is this an '{..} or '[..] irrefutable quoted patterns?
Is this an '{..} or '[..] irrefutable quoted patterns?
Value parameters
- implicits
-
The implicits of the unapply
- pt
-
The scrutinee type
- unapp

Attributes
True if we can assume that the two unapply methods are the same. That is, given the same parameter, they return the same result.
True if we can assume that the two unapply methods are the same. That is, given the same parameter, they return the same result.
We assume that unapply methods are pure, but the same method may be called with different prefixes, thus behaving differently.
Attributes
Is tp1 a subtype of tp2?
Is tp1 a subtype of tp2?
Attributes
The space of a not covered by b
The space of a not covered by b
Attributes
Return the space that represents the pattern pat
Return the space that represents the pattern pat
Attributes
Space of the pattern: unapplySeq(a, b, c: _*)
Space of the pattern: unapplySeq(a, b, c: _*)
Attributes
Whether the counterexample is satisfiable. The space is flattened and non-empty.

Attributes
Return the underlying type of non-module, non-constant, non-enum case singleton types. Also widen ExprType to its result type, and rewrap any annotation wrappers. For example, with val opt = None, widen opt.type to None.type.
