GI.Gio.Objects.MemoryInputStream
Description
MemoryInputStream is a class for using arbitrary
memory chunks as input for GIO streaming input operations.
As of GLib 2.34, MemoryInputStream implements
PollableInputStream.
Synopsis
- newtype MemoryInputStream = MemoryInputStream (ManagedPtr MemoryInputStream)
- class GObject o => IsMemoryInputStream o
- toMemoryInputStream :: (MonadIO m, IsMemoryInputStream o) => o -> m MemoryInputStream
- noMemoryInputStream :: Maybe MemoryInputStream
- memoryInputStreamAddBytes :: (HasCallStack, MonadIO m, IsMemoryInputStream a) => a -> Bytes -> m ()
- memoryInputStreamAddData :: (HasCallStack, MonadIO m, IsMemoryInputStream a) => a -> ByteString -> Maybe DestroyNotify -> m ()
- memoryInputStreamNew :: (HasCallStack, MonadIO m) => m MemoryInputStream
- memoryInputStreamNewFromBytes :: (HasCallStack, MonadIO m) => Bytes -> m MemoryInputStream
- memoryInputStreamNewFromData :: (HasCallStack, MonadIO m) => ByteString -> Maybe DestroyNotify -> m MemoryInputStream
