Reads the value associated with the current fiber.
Reads the value associated with the current fiber. Returns initial value if
no value was set
or inherited from parent.
Atomically sets the value associated with the current fiber and returns the old value.
Atomically modifies the FiberRef
with the specified function and returns
the old value.
Atomically modifies the FiberRef
with the specified partial function and
returns the old value.
Atomically modifies the FiberRef
with the specified partial function and
returns the old value.
If the function is undefined on the current value it doesn't change it.
Returns an IO
that runs with value
bound to the current fiber.
Returns an IO
that runs with value
bound to the current fiber.
Guarantees that fiber data is properly restored via bracket
.
Atomically modifies the FiberRef
with the specified function, which computes
a return value for the modification.
Atomically modifies the FiberRef
with the specified function, which computes
a return value for the modification. This is a more powerful version of
update
.
Atomically modifies the FiberRef
with the specified partial function, which computes
a return value for the modification if the function is defined in the current value
otherwise it returns a default value.
Atomically modifies the FiberRef
with the specified partial function, which computes
a return value for the modification if the function is defined in the current value
otherwise it returns a default value.
This is a more powerful version of updateSome
.
Sets the value associated with the current fiber.
Returns a ThreadLocal
that can be used to interact with this FiberRef
from side effecting code.
Returns a ThreadLocal
that can be used to interact with this FiberRef
from side effecting code.
This feature is meant to be used for integration with side effecting code, that needs to access fiber specific data,
like MDC contexts and the like. The returned ThreadLocal
will be backed by this FiberRef
on all threads that are
currently managed by ZIO, and behave like an ordinary ThreadLocal
on all other threads.
Atomically modifies the FiberRef
with the specified function.
Atomically modifies the FiberRef
with the specified function and returns
the result.
Atomically modifies the FiberRef
with the specified partial function.
Atomically modifies the FiberRef
with the specified partial function.
If the function is undefined on the current value it doesn't change it.
Atomically modifies the FiberRef
with the specified partial function.
Atomically modifies the FiberRef
with the specified partial function.
If the function is undefined on the current value it returns the old value
without changing it.
Fiber's counterpart for Java's
ThreadLocal
. Value is automatically propagated to child on fork and merged back in after joining child.result
will be equal to "Hi!" as changes done by child were merged on join.FiberRef#make also allows specifying how the values will be combined when joining. By default this will use the value of the joined fiber. for { fiberRef <- FiberRef.make(0, math.max) child <- fiberRef.update(_ + 1).fork _ <- fiberRef.update(_ + 2) _ <- child.join value <- fiberRef.get } yield value }}}
value
will be 2 as the value in the joined fiber is lower and we specifiedmax
as our combine function.
