Type Alias OptionalBody 

pub type OptionalBody<T> = Either<FullBody<T>, EmptyBody>;

Available on crate feature http only.

A body type representing an optional payload.

This is a convenience alias for http_body_util::Either<FullBody<T>, EmptyBody>, used when an HTTP request or response may or may not carry a body.

The Left variant holds a FullBody<T> for when a payload is present, while the Right variant holds an EmptyBody for when it is absent.

Examples

use spin_sdk::http::{OptionalBody, FullBody, EmptyBody};
use bytes::Bytes;

// With a body
let with_body: OptionalBody<Bytes> =
    http_body_util::Either::Left(FullBody::new(Bytes::from("hello")));

// Without a body
let without_body: OptionalBody<Bytes> =
    http_body_util::Either::Right(EmptyBody::new());

Aliased Type

pub enum OptionalBody<T> {
    Left(Full<T>),
    Right(Empty<Bytes>),
}
