Trait WriteExt

}

Write bytes to a writer.

Extension trait for all Write types.

Provided Methods

fn write_buf<B>(&mut self, buf: B) -> Result<(), Self::Error>

where B: Buf,

Write buf to the writer advancing it appropriately.

fn write_buf_all<B>(&mut self, buf: B) -> Result<(), Self::Error>

where B: Buf,

Write buf to the writer advancing it until all of it has been written.

This method will try to write buf repeatedly until either a) buf has no more data, b) an error occurs, c) the writer cannot accept any more bytes.

fn flush(&mut self) -> Result<(), Self::Error>

Flush this writer ensuring all bytes reach their destination.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Create a “by reference” adapter that takes the current instance of Write by mutable reference.

fn transaction( self, kind: WriteTransactionKind<'_>, ) -> WriteTransactionVariant<'_, Self>

where Self: Sized,

Available on crate feature alloc only.

Create a transaction that uses this writer.

This is a convenience wrapper for: WriteTransactionVariant::new()

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
