Control.Concurrent.STM.TArray

Description

TArrays: transactional arrays, for use in the STM monad

Synopsis

Documentation

data TArray i e Source

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

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

Instances
