Struct parity_wasm::elements::CountedWriter

pub struct CountedWriter<'a, W: 'a + Write> { /* fields omitted */ }

Helper struct to write payload which is preceded by it's own length in bytes.

Methods

impl<'a, W: 'a + Write> CountedWriter<'a, W>

pub fn new(writer: &'a mut W) -> Self

New counted writer on top of the given serial writer

pub fn done(self) -> Result<()>

Finish counted writer routing, which writes accumulated length and actual payload.

Trait Implementations

impl<'a, W: Debug + 'a + Write> Debug for CountedWriter<'a, W>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<'a, W: 'a + Write> Write for CountedWriter<'a, W>

fn write(&mut self, buf: &[u8]) -> Result<usize>

Write a buffer into this object, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this write.

fn write_fmt(&mut self, fmt: Arguments) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

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