Map-key encoding contract used by MutableMap.

Required Methods

fn decode_key(field: FieldView<'a>) -> Option<Self>

fn detect_key(field: FieldView<'a>) -> Option<&'a [u32]>

fn encode_key(&self, buffer: &mut Buffer) -> Result<Unit, MutableError>

fn key_kind() -> MutableMapKeyKind

fn write_key_bytes<'b>(&'b self, scratch: &'b mut [u8; 8]) -> &'b [u8]

Provided Methods

fn borrowed_key_bytes(&self) -> Option<&[u8]>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
