SliceWriter

Struct SliceWriter 

pub struct SliceWriter<'a> {
    pub buf: &'a mut [u8],
    pub pos: usize,
}
Expand description

A core::fmt::Write sink over a fixed-size byte slice.

Used to format a core::panic::PanicInfo into a stack buffer without heap allocation. Truncates silently when the buffer fills — acceptable for a best-effort panic message capture.

Fields§

§buf: &'a mut [u8]§pos: usize
