Trait Serializer

Serialize an HTTP response body

Serializer values use one or more Serde serializers to perform the actual serialization.

The Serializer values are also responsible for mapping content-type values to Serde serializers.

Required Associated Types

type Format: Clone + Send + Sync + 'static

A token used by Serializer implementations to identify the specific serialization format to use when encoding a value.

Required Methods

fn lookup(&self, name: &str) -> Option<ContentType<Self::Format>>

Lookup a serializer and HeaderValue for the given Content-Type string.

fn serialize<T>( &self, value: &T, format: &Self::Format, context: &SerializerContext<'_>, ) -> Result<Bytes, Error>

where T: Serialize,

Serialize the value using the specified format.

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.
