Struct SmallHex 

pub struct SmallHex { /* private fields */ }

A short, inline snapshot of offending bytes for diagnostics — never a heap allocation on the hot error path, and capped so a hostile stream cannot make an error message unbounded.

Implementations

impl SmallHex

pub const CAP: usize = 16

Maximum captured bytes; enough to identify a magic/signature.

pub fn new(bytes: &[u8]) -> Self

Capture up to SmallHex::CAP bytes from bytes (a longer slice is truncated — the prefix is what identifies a signature). Never panics.

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

The captured bytes.

pub fn is_empty(&self) -> bool

True when nothing was captured.
