Cursor

Struct Cursor 

Source
pub struct Cursor<'a> { /* private fields */ }
Expand description

A zero-copy cursor over an in-memory byte slice.

Avoids std::io::Cursor and its wide error surface; only the two error cases above can ever occur during TL deserialization.

Implementations§

Source§

impl<'a> Cursor<'a>

Source

pub fn from_slice(buf: &'a [u8]) -> Self

Create a cursor positioned at the start of buf.

Source

pub fn pos(&self) -> usize

Current byte offset.

Source

pub fn remaining(&self) -> usize

Remaining bytes.

Source

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

Read a single byte.

Source

pub fn read_exact(&mut self, out: &mut [u8]) -> Result<()>

Read exactly buf.len() bytes.

Source

pub fn read_to_end(&mut self, out: &mut Vec<u8>) -> usize

Consume all remaining bytes into out.
