Enum EndpointLabel

pub enum EndpointLabel {
    Exact,
    MatchedPath,
    MatchedPathWithFallbackFn(for<'f> fn(&'f str) -> String),
}

Determines how endpoints are reported.

Variants

Exact

The reported endpoint label is always the fully qualified uri path that has been requested.

MatchedPath

The reported endpoint label is determined by first trying to extract and return axum::extract::MatchedPath, and if that fails (typically on nested routes) it falls back to EndpointLabel::Exact behavior. This is the default option.

MatchedPathWithFallbackFn(for<'f> fn(&'f str) -> String)

Same as EndpointLabel::MatchedPath, but instead of falling back to the exact uri called, it’s given to a user-defined fallback function, that is expected to produce a String, which is then reported to Prometheus.
