}

Helper trait for reading OpenTimestamps primitives from a byte stream.

Required Methods

fn decode_byte(&mut self) -> Result<u8, DecodeError>

Decodes a single byte from the reader.

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

Provided Methods

fn decode_ranged<T: Decode + PartialOrd>( &mut self, range: impl RangeBounds<T>, ) -> Result<T, DecodeError>

Decodes a value and ensures it falls within the supplied range.

fn assert_magic(&mut self) -> Result<(), DecodeError>

Verifies that the next bytes in the stream match the magic sequence.

fn decode<T: Decode>(&mut self) -> Result<T, DecodeError>

Decodes a value implementing the Decode trait.

fn decode_trailing<T: Decode>(&mut self) -> Result<Option<T>, DecodeError>

Decodes a trailing optional value implementing the Decode trait.

See Decode::decode_trailing for details and caveats.

fn decode_in<T: DecodeIn<A>, A: Allocator>( &mut self, alloc: A, ) -> Result<T, DecodeError>

Decodes a value implementing the Decode trait.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
