Expand description

Trait that allows zero-copy write of value-references to slices in LE format.

Implementations should override using_encoded for value types and encode_to and size_hint for allocating types. Wrapper types should override all methods.

Provided Methods§

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

This method is used inside default implementation of encode to avoid re-allocations.

fn encode_to<T>(&self, dest: &mut T)where T: Output + ?Sized,

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8, Global> ⓘ

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> Rwhere F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

Should be used when the encoded data isn’t required.

This works by using a special [Output] that only tracks the size. So, there are no allocations inside the output. However, this can not prevent allocations that some types are doing inside their own encoding.
