Expand description

Trait governing how to encode a map entry.

Required Associated Types§

Source

type Cx: ?Sized + Context

Context associated with the encoder.

Source

type Ok

Result type of the encoder.

Source

type EncodeKey<'this>: Encoder<Cx = Self::Cx, Ok = Self::Ok, Error = <Self::Cx as Context>::Error, Mode = <Self::Cx as Context>::Mode> where Self: 'this

The encoder returned when advancing the map encoder to encode the key.

Source

type EncodeValue<'this>: Encoder<Cx = Self::Cx, Ok = Self::Ok, Error = <Self::Cx as Context>::Error, Mode = <Self::Cx as Context>::Mode> where Self: 'this

The encoder returned when advancing the map encoder to encode the value.

Required Methods§

Source

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

Return the encoder for the key in the entry.

Source

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

Return encoder for value in the entry.

Source

fn finish_entry(self) -> Result<Self::Ok, <Self::Cx as Context>::Error>

Stop encoding this pair.

Provided Methods§

Source

fn insert_entry<K, V>( self, key: K, value: V, ) -> Result<Self::Ok, <Self::Cx as Context>::Error>
where Self: Sized, K: Encode<<Self::Cx as Context>::Mode>, V: Encode<<Self::Cx as Context>::Mode>,

Insert the pair immediately.

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.
