Struct PaddedBuf 

struct PaddedBuf<'a> {
    real: &'a [u8],
    pad: usize,
}

A slice followed by a run of zero bytes.

Lets a decoder walk an object’s framing and advance past a payload that has not arrived yet, so the framer can learn an object’s total wire length without buffering it. Only fields decoded from the real prefix are trustworthy; the caller checks that before using the result, and picks the pad width from what the decode path may copy — see ObjectFramer::measuring_pad.

Fields

real: &'a [u8]

pad: usize

Trait Implementations

impl Buf for PaddedBuf<'_>

fn remaining(&self) -> usize
