Expand description

A trait for values that can be decoded from bytes deterministically.

Required methods

Reads bytes from the reader and returns the decoded value.

When possible, calling decode_into will often be more efficient since it lets the caller reuse memory to avoid allocating for fields with types such as Vec<T>.

Provided methods

Reads bytes from the reader and mutates self to the decoded value.

This is often more efficient than calling decode when reading fields with heap-allocated types such as Vec<T> since it can reuse the memory already allocated in self.

When possible, implementations should recursively call decode_into on any child fields.

The default implementation of decode_into simply calls decode for ease of implementation, but should be overridden when in-place decoding is possible.
