Struct RequestMutation 

pub struct RequestMutation {
    pub headers: Vec<(String, String)>,
    pub body: Option<Bytes>,
}

An owned, mutable view of an outgoing request’s headers and body, handed to a ModifyRequestFn.

Headers are a Vec<(String, String)> rather than a map, so order is preserved and duplicate header names are kept as separate entries rather than collapsed.

Fields

headers: Vec<(String, String)>

The request’s headers, in wire order.

body: Option<Bytes>

The request’s body, if any and if readable.

None here means there was either no body to begin with, or the body exists but couldn’t be read without consuming a stream (the same limitation HttpAcl::is_valid’s body parameter already has). Leaving this as None on the way out never clears an existing body - it is only ever an instruction to leave the body untouched, so a ModifyRequestFn that only wants to touch headers can never accidentally truncate a body it was never shown. Set it to Some(bytes) to replace the body wholesale.
