Extension methods for Decoder.

Required Methods

fn take_slot<T>(&mut self) -> Result<Slot<'de, T>, DecodeError>

Takes enough chunks for a T, returning a Slot of the taken value.

fn take_slice_slot<T>( &mut self, len: usize, ) -> Result<Slot<'de, [T]>, DecodeError>

Takes enough chunks for a slice of T, returning a Slot of the taken slice.

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

where T: Decode<Self, Constraint = ()>,

Decodes an owned value from the decoder without finishing it.

On success, returns Ok of an owned value. Returns Err if decoding failed.

fn decode_prefix_with_constraint<T>( &mut self, constraint: T::Constraint, ) -> Result<T, DecodeError>

where T: Decode<Self>,

Decodes an owned value from the decoder with some constraint without finishing it.

On success, returns Ok of an owned value. Returns Err if decoding failed.

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

where T: Decode<Self, Constraint = ()>,

Decodes an owned value from the decoder and finishes it.

On success, returns Ok of an owned value. Returns Err if decoding failed.

fn decode_with_constraint<T>( &mut self, constraint: T::Constraint, ) -> Result<T, DecodeError>

where T: Decode<Self>,

Decodes an owned value from the decoder with some constraint and finishes it.

On success, returns Ok of an owned value. Returns Err if decoding failed.

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.
