Implementations

impl<'a> Reader<'a>

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

pub fn data(&self) -> &'a [u8]

pub fn eof(&self) -> bool

pub fn remaining(&self) -> usize

pub fn varint(&mut self) -> Result<u64>

Read an unsigned varint, up to 10 bytes (uint64 range).

pub fn zigzag32(&mut self) -> Result<i32>

Decode a zigzag varint as a 32-bit signed integer.

pub fn zigzag64(&mut self) -> Result<i64>

Decode a zigzag varint as a 64-bit signed integer.

pub fn fixed32(&mut self) -> Result<u32>

pub fn fixed64(&mut self) -> Result<u64>

pub fn float(&mut self) -> Result<f32>

pub fn double(&mut self) -> Result<f64>

pub fn bytes(&mut self) -> Result<Vec<u8>>

Length-prefixed bytes; returns a copy.

pub fn bytes_view(&mut self) -> Result<&'a [u8]>

Length-prefixed bytes; returns a borrow into the underlying buffer.

Guards against attacker-supplied length-prefix overflow per HARDENING.md §API contract item 3: a 10-byte varint of 2^64-1 would wrap pos + len to a small value and slip past a naive bounds check, then trip a slice-indexing panic. Compute the end offset with checked_add and reject before slicing.

pub fn string(&mut self) -> Result<String>

UTF-8 length-prefixed string.

pub fn tag(&mut self) -> Result<(u32, WireType)>

Decode a tag varint into (field_number, wire_type).

pub fn skip(&mut self, wire_type: WireType) -> Result<()>

Skip the value of a field with the given wire type.
