Struct CMsgBuilder

source

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

Expand description

Helper to construct control message.

Implementations§

source §

impl<'a> CMsgBuilder<'a>

source

pub fn new(buffer: &'a mut [u8]) -> Self

Create CMsgBuilder with the given buffer. The buffer will be zeroed on creation.

§Panics

This function will panic if the buffer is too short or not properly aligned.

source

pub fn finish(self) -> usize

Finishes building, returns length of the control message.

source

pub fn try_push<T>(&mut self, level: i32, ty: i32, value: T) -> Option<()>

Try to append a control message entry into the buffer. If the buffer does not have enough space or is not properly aligned with the value type, returns None.
