pub fn done(&self) -> bool

pub fn read_varint(&mut self) -> Option<u64>

Reads a base-128 varint. Returns None on truncation.

pub fn next_key(&mut self) -> Option<(u32, u8)>

Reads a field key, returning (field_number, wire_type).

pub fn read_len(&mut self) -> Option<&'a [u8]>

Reads a length-delimited byte slice.

pub fn read_fixed32(&mut self) -> Option<u32>

pub fn read_fixed64(&mut self) -> Option<u64>

pub fn skip(&mut self, wire: u8) -> Option<()>

Skips the body of a field with the given wire type. Returns None on a malformed/unsupported wire type.
