}

Trait governing how to decode a map entry.

Required Associated Types

type Cx: Context<Error = Self::Error, Allocator = Self::Allocator>

Context associated with the decoder.

type Error

Error associated with decoding.

type Allocator: Allocator

The allocator associated with the decoder.

type Mode: 'static

The mode of the decoder.

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

The decoder to use for a tuple field index.

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

The decoder to use for a tuple field value.

Required Methods

fn cx(&self) -> Self::Cx

Access the context associated with the decoder.

fn decode_key(&mut self) -> Result<Self::DecodeKey<'_>, Self::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::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".
