Struct Cur 

pub struct Cur<'a> {
    pub pos: usize,
    /* private fields */
}

A bounds-checked cursor over untrusted bytes.

Fields

pos: usize

Current position.

Implementations

impl<'a> Cur<'a>

pub fn new(b: &'a [u8]) -> Cur<'a>

A cursor at the start of b.

pub fn done(&self) -> bool

At the end?

pub fn uv(&mut self) -> Result<u64, FileError>

One varint.

pub fn u32v(&mut self) -> Result<u32, FileError>

One varint as a u32.

pub fn len(&mut self) -> Result<usize, FileError>

One varint as a length bounded by the remaining bytes.

pub fn count(&mut self, max: u64) -> Result<usize, FileError>

One varint as a count, sanity-bounded by max.

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

One byte.

pub fn bytes(&mut self, n: usize) -> Result<&'a [u8], FileError>

n raw bytes.

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

A length-prefixed byte string.
