tryPutMVar :: MVar a -> a -> IO Bool
base Control.Concurrent.MVar GHC.MVar, base-prelude BasePrelude, ghc-internal GHC.Internal.Control.Concurrent.MVar GHC.Internal.MVar, rebase Rebase.Prelude, hledger Hledger.Cli.Script
A non-blocking version of putMVar. The tryPutMVar function attempts to put the value a into the MVar, returning True if it was successful, or False otherwise.
tryPutMVar :: PrimMonad m => MVar (PrimState m) a -> a -> m Bool
primitive Data.Primitive.MVar
A non-blocking version of putMVar. The tryPutMVar function attempts to put the value a into the MVar, returning True if it was successful, or False otherwise.
tryPutMVar :: MonadIO m => MVar a -> a -> m Bool
unliftio UnliftIO.MVar
Lifted tryPutMVar.
tryPutMVar :: MonadBase IO m => MVar a -> a -> m Bool
lifted-base Control.Concurrent.MVar.Lifted
Generalized version of tryPutMVar.
tryPutMVar :: MonadIO m => MVar a -> a -> m Bool
relude Relude.Lifted.Concurrent, universum Universum.Lifted.Concurrent
Lifted to MonadIO version of tryPutMVar.
tryPutMVar :: MonadConc m => MVar m a -> a -> m Bool
concurrency Control.Concurrent.Classy.MVar Control.Monad.Conc.Class
Attempt to put a value in a MVar non-blockingly, returning True (and filling the MVar) if there was nothing there, otherwise returning False.
tryPutMVar :: NFData a => MVar a -> a -> IO Bool
strict-concurrency Control.Concurrent.MVar.Strict
A non-blocking version of putMVar. The tryPutMVar function attempts to put the value a into the MVar, returning True if it was successful, or False otherwise.
TryPutMVar :: MVarId -> Bool -> [ThreadId] -> ThreadAction
dejafu Test.DejaFu.Conc Test.DejaFu.Types
Try to put into a MVar, possibly waking up some threads.

tryPutMVar' :: MVar' a -> a -> IO Bool
strict-mutable-base Control.Concurrent.MVar.Strict
tryPutMVar for an MVar'. Evaluates the new value to WHNF.
