Struct RequestContext 

pub struct RequestContext {
    pub request_id: String,
    pub client_addr: Option<SocketAddr>,
    pub method: String,
    pub metadata: HashMap<String, String>,
    pub start_time: Instant,
    pub attributes: HashMap<String, Box<dyn Any + Send + Sync>>,
}

Context that travels through the middleware pipeline.

Middleware can read/write metadata (string key-value) or store arbitrary typed data in attributes.

Fields

request_id: String

Unique request identifier (UUID v4).

client_addr: Option<SocketAddr>

Remote peer address, if known.

method: String

Logical method / query type (e.g. "GET", "PUT", "QUERY").

metadata: HashMap<String, String>

Extensible string metadata.

start_time: Instant

When the request started.

attributes: HashMap<String, Box<dyn Any + Send + Sync>>

Typed attributes that middleware can set/get.

Implementations

impl RequestContext

pub fn new(method: impl Into<String>) -> Self

pub fn with_client_addr(self, addr: SocketAddr) -> Self

pub fn with_metadata( self, key: impl Into<String>, value: impl Into<String>, ) -> Self

pub fn set_attribute<T: Any + Send + Sync>( &mut self, key: impl Into<String>, value: T, )

Store a typed attribute.

pub fn get_attribute<T: Any + Send + Sync>(&self, key: &str) -> Option<&T>

Retrieve a typed attribute by reference.

pub fn elapsed(&self) -> Duration
