    pub component: Option<String>,
    pub tracing: HashMap<String, String>,
}

Implementations

impl Context

pub fn link_name(&self) -> &str

Get link name from the request.

While link name should in theory always be present, it is not natively included in Context yet, so we must retrieve it from headers on the request.

Note that in certain (older) versions of wasmCloud it is possible for the link name to be missing though incredibly unlikely (basically, due to a bug). In the event that the link name was not properly stored on the context ‘default’ (the default link name) is returned as the link name.
