ResponseSerializer Trait

A trait for defining custom response serialization logic. Use this when you want to transform a domain object into a specific API response format, such as hiding fields, renaming keys, or flattening structures.

Type Parameters

• T: The input type to serialize

Associated Types

• Output: The serialized output type (must implement Serialize)

Example

struct UserResponseSerializer;
impl ResponseSerializer<User> for UserResponseSerializer {
    type Output = UserResponse;
    fn serialize(value: User) -> Self::Output {
        UserResponse {
            id: value.id,
            name: value.name,
            // password is hidden
        }
    }
}

Required Associated Types

type Output: Serialize

Required Methods

fn serialize(value: T) -> Self::Output

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.
