Trait Codec

Source

pub trait Codec {
    type Serializer: ShapeSerializer;
    type Deserializer<'a>: ShapeDeserializer;

    // Required methods
    fn create_serializer(&self) -> Self::Serializer;
    fn create_deserializer<'a>(&self, input: &'a [u8]) -> Self::Deserializer<'a>;
}

Expand description

A codec for a specific serialization format.

Codecs are responsible for creating ShapeSerializer and ShapeDeserializer instances that can serialize and deserialize shapes to and from a specific format.

§Examples

Implementing a custom codec:

use aws_smithy_schema::codec::Codec;
use aws_smithy_schema::serde::{ShapeSerializer, ShapeDeserializer};

struct MyCodec {
    // codec configuration
}

impl Codec for MyCodec {
    type Serializer = MySerializer;
    type Deserializer = MyDeserializer;

    fn create_serializer(&self) -> Self::Serializer {
        MySerializer::new()
    }

    fn create_deserializer(&self, input: &[u8]) -> Self::Deserializer {
        MyDeserializer::new(input)
    }
}
