Struct anchor::ScratchOutput

pub struct ScratchOutput<const MAX_SIZE: usize = 64> { /* private fields */ }

A scratch pad based OutputBuffer.

Uses a statically sized inlined buffer. For serializing multiple messages in a row, the buffer can be reset if needed.

Implementations

impl<const MAX_SIZE: usize> ScratchOutput<MAX_SIZE>

pub fn result(&self) -> &[u8]

Retrieve the currently built buffer

pub fn reset(&mut self)

Reset the buffer, clearing it

pub const fn new() -> Self

Create a new buffer

Trait Implementations

fn output(&mut self, buf: &[u8])

Append bytes to the buffer

fn cur_position(&self) -> Self::Cursor

Retrieve the cursor representing the position of the last appended byte

fn update(&mut self, cursor: Self::Cursor, value: u8)

Replace the byte at the cursor position with a new value

fn data_since(&self, cursor: Self::Cursor) -> &[u8]
