Control.Concurrent.Classy.STM.TArray

Description

TArrays: transactional arrays, for use in STM-like monads.

Deviations: TArray as defined here does not have an Eq instance, this is because the MonadSTM TVar type does not have an Eq constraint.

Synopsis

Documentation

data TArray stm i e Source #

TArray is a transactional array, supporting the usual MArray interface for mutable arrays.

It is currently implemented as Array ix (TVar stm e), but it may be replaced by a more efficient implementation in the future (the interface will remain the same, however).

Instances

MonadSTM stm => MArray (TArray stm) e stm Source #
