Struct VecOutputTarget 

pub struct VecOutputTarget<'a> { /* private fields */ }

A wrapper around a Vec<u8> that implements OutputTarget.

The implementation will automatically grow the Vec as needed.

Trait Implementations

impl<'a> Debug for VecOutputTarget<'a>

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

Formats the value using the given formatter.

impl<'a> From<&'a mut Vec<u8>> for VecOutputTarget<'a>

fn from(value: &'a mut Vec<u8>) -> Self

Creates a new VecOutputTarget that wraps the provided vector.

impl OutputTarget for VecOutputTarget<'_>

fn remaining(&self) -> usize

Returns the number of unwritten bytes currently remaining in the target.

fn write_byte(&mut self, byte: u8) -> Result<()>

Attempts to write the provided byte into this target.

fn write_bytes_exact(&mut self, bytes: &[u8]) -> Result<()>

Attempts to write the provided bytes into this target.

fn write_bytes_into_reserved_exact( &mut self, reservation: &mut Reservation, bytes: &[u8], ) -> Result<()>

Attempts to write the provided bytes into a reserved chunk of memory within this target.

fn reserve_space(&mut self, count: usize) -> Result<Reservation>

Reserves a chunk of memory in the target that can be written to later, and advances past it.
