Trait PrepareBody 

pub trait PrepareBody:
    Sealed<(Parts,)>
    + Send
    + Sync
    + 'static {
    // Required method
    fn prepare_body(
        &self,
        parts: &Parts,
        is_end_stream: bool,
        size_hint: &SizeHint,
    ) -> Option<CollectOptions>;
}

Available on crate features http and std only.

Decide whether and how to collect a body for replay.

Implemented for functions taking request parts, the body’s end-of-stream assertion, and its size hint, and returning optional collection limits.

Required Methods

fn prepare_body( &self, parts: &Parts, is_end_stream: bool, size_hint: &SizeHint, ) -> Option<CollectOptions>

Return collection options, or decline replay preparation.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
