Struct constriction::backends::InfallibleCallbackWriteWords

pub struct InfallibleCallbackWriteWords<Callback> { /* private fields */ }

Adapter that turns an infallible callback into an infallible data sink.

Wraps a callback function from Word to () and implements WriteWords<Word, WriteError=Infallible> by calling the callback each time a client writes to it.

See also FallibleCallbackWriteWords, and module-level documentation for a detailed usage example.

Implementations

impl<Callback> InfallibleCallbackWriteWords<Callback>

pub fn new(write_callback: Callback) -> Self

Creates the adapter for the provided callback.

pub fn into_inner(self) -> Callback

Consumes the adapter and returns the provided callback.

Trait Implementations

impl<Callback: Clone> Clone for InfallibleCallbackWriteWords<Callback>

fn clone(&self) -> InfallibleCallbackWriteWords<Callback>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<Callback: Debug> Debug for InfallibleCallbackWriteWords<Callback>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<Word, Callback> WriteWords<Word> for InfallibleCallbackWriteWords<Callback>

where Callback: FnMut(Word),

type WriteError = Infallible

The error type that can occur when writing to the data sink, or Infallible.

fn write(&mut self, word: Word) -> Result<(), Infallible>

Writes a single Word to the data sink and advances the state of the data sink accordingly (i.e., so that the next write won’t overwrite the current Word).

fn extend_from_iter( &mut self, iter: impl Iterator<Item = Word> ) -> Result<(), Self::WriteError>

Writes a sequence of Words to the data sink, short-circuiting on error.

fn maybe_full(&self) -> bool

Returns true if the data sink could be full
