Trait ContextSmuggler

pub trait ContextSmuggler<S> {
    // Required methods
    fn inject_ctx(&mut self, ctx: Context<S>);
    fn try_extract_ctx(&mut self) -> Option<Context<S>>;
}

Trait to be implemented for any request that can “smuggle” Contexts.

• if the http feature is enabled it will already be implemented for rama_http_types::Request;
• for types that do have this capability and you work with tower services which do not care about the specific type of the request that passes through it, you can make use of RequestStatePair using the tower map-request capabilities, to easily swap between the pair and direct request format.

Required Methods

fn inject_ctx(&mut self, ctx: Context<S>)

inject the context into the smuggler.

fn try_extract_ctx(&mut self) -> Option<Context<S>>

try to extract the smuggled context out of the smuggle, which is only possible once.
