Struct RequestContext 

pub struct RequestContext {
    pub ip: Option<IpAddr>,
    pub user_agent: Option<String>,
    pub request_id: Option<String>,
}

What a request carries before the reverse lookup has run.

An extractor rather than three Extensions at each call site: a handler that records an audit row wants all of this or none of it, and gathering it in one place is what keeps User-Agent’s truncation rule (below) from being re-decided per handler. Resolve it into a ClientContext with Auditor::client.

Fields

ip: Option<IpAddr>

user_agent: Option<String>

request_id: Option<String>

Implementations

impl RequestContext

pub fn from_parts(parts: &Parts) -> Self

Reads the address the filter middleware resolved, plus the two headers.

Free of the request body, so this composes with AcmeRequest<T> — which consumes it — in the usual axum order.

pub fn from_request<B>(request: &Request<B>) -> Self

Same, from a whole request.

verify_jws needs this: it is handed the Request and consumes it into a body string, so it has to read the context before the point where the extractor machinery would hand it Parts.

Trait Implementations

impl Clone for RequestContext

fn clone(&self) -> RequestContext

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RequestContext

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for RequestContext

fn default() -> RequestContext

Returns the “default value” for a type.

impl<S: Send + Sync> FromRequestParts<S> for RequestContext

type Rejection = Infallible

If the extractor fails it’ll use this “rejection” type. A rejection is a kind of error that can be converted into a response.

async fn from_request_parts( parts: &mut Parts, _state: &S, ) -> Result<Self, Self::Rejection>

Perform the extraction.
