Trait governing how to decode a map entry.

Required Associated Types

type Cx: ?Sized + Context

Context associated with the decoder.

type DecodeKey<'this>: Decoder<'de, Cx = Self::Cx, Error = <Self::Cx as Context>::Error, Mode = <Self::Cx as Context>::Mode> where Self: 'this

The decoder to use for a tuple field index.

type DecodeValue: Decoder<'de, Cx = Self::Cx, Error = <Self::Cx as Context>::Error, Mode = <Self::Cx as Context>::Mode>

The decoder to use for a tuple field value.

Required Methods

fn decode_key( &mut self, ) -> Result<Self::DecodeKey<'_>, <Self::Cx as Context>::Error>

Return the decoder for the first value in the pair.

If this is a map the first value would be the key of the map, if this is a struct the first value would be the field of the struct.

fn decode_value(self) -> Result<Self::DecodeValue, <Self::Cx as Context>::Error>

Decode the second value in the pair..

Provided Methods

fn size_hint(&self) -> SizeHint

Get a size hint for the size of the map being decoded.

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.
