Extension methods for Encoder.

Required Methods

fn preallocate<T>(&mut self, len: usize) -> Preallocated<'_, Self, T>

Pre-allocates space for a slice of elements.

fn encode_next_slice<T>(&mut self, values: &mut [T]) -> Result<(), EncodeError>

where T: Encode<Self>,

Encodes a slice of elements.

Returns Err if encoding failed.

fn encode_next<T>(&mut self, value: &mut T) -> Result<(), EncodeError>

where T: Encode<Self>,

Encodes a value.

Returns Err if encoding 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.
