Struct ConstReader 

pub struct ConstReader<'a> { /* private fields */ }

Const-friendly cursor for reading primitives out of a byte buffer.

Reads return slices borrowed from the underlying buffer, which keeps the reader allocation-free; callers can .to_owned() if they need ownership.

Implementations

impl<'a> ConstReader<'a>

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

pub const fn read_bytes(&mut self, n: usize) -> Option<&'a [u8]>

pub const fn read_u16_le(&mut self) -> Option<u16>

pub const fn read_u64_le(&mut self) -> Option<u64>

pub const fn read_str(&mut self) -> Option<&'a str>

pub const fn read_str_opt(&mut self) -> Option<Option<&'a str>>

Reads an optional string, encoding three states: None when the buffer is exhausted, Some(None) for an absent string, and Some(Some(_)) for a present string.

pub const fn skip(&mut self, n: usize) -> Option<()>
