Struct CanonicalReader 

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

Strict reader for the fixed-width canonical grammar.

Implementations

impl<'a> CanonicalReader<'a>

pub fn new(bytes: &'a [u8]) -> Result<Self, CanonicalError>

Construct a reader after enforcing the top-level payload bound.

pub fn raw(&mut self, length: usize) -> Result<&'a [u8], CanonicalError>

Read an exact number of bytes.

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

Read one unsigned byte.

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

Read one big-endian unsigned 32-bit integer.

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

Read one big-endian unsigned 64-bit integer.

pub fn text(&mut self) -> Result<&'a str, CanonicalError>

Read one bounded length-prefixed UTF-8 value.

pub fn finish(self) -> Result<(), CanonicalError>

Reject unconsumed trailing bytes.
