Struct JsonCodec 

pub struct JsonCodec { /* private fields */ }

JSON codec for schema-based serialization and deserialization.

This codec implements the Smithy JSON protocol serialization rules, with configurable behavior for different protocol variants (e.g., AWS JSON RPC vs REST JSON).

Examples

use aws_smithy_json::codec::{JsonCodec, JsonCodecSettings};
use aws_smithy_schema::codec::Codec;
use aws_smithy_types::date_time::Format;

// Create codec with default settings (REST JSON style)
let codec = JsonCodec::new(JsonCodecSettings::default());

// Create codec for AWS JSON RPC (no jsonName, epoch-seconds timestamps)
let codec = JsonCodec::new(JsonCodecSettings {
    use_json_name: false,
    default_timestamp_format: Format::EpochSeconds,
    allow_unknown_union_members: false,
});

// Use the codec
let _serializer = codec.create_serializer();
let _deserializer = codec.create_deserializer(b"{}");
