Struct pavex::telemetry::ServerRequestId

source ·
pub struct ServerRequestId(/* private fields */);
Expand description

A unique identifier generated for each incoming request.

It is a TypeId. The prefix is always sri, followed by an underscore and UUIDv7 in base32 encoding. For example:

 sri_2x4y6z8a0b1c2d3e4f5g6h7j8k
 └─┘ └────────────────────────┘
prefix    uuid suffix (base32)

§Example

use http::{HeaderName, HeaderValue};
use pavex::response::Response;
use pavex::telemetry::ServerRequestId;

pub async fn request_handler(request_id: ServerRequestId) -> Response {
    // Add the request id as a header on the outgoing response
    Response::ok()
        .insert_header(
            HeaderName::from_static("X-Request-Id"),
            request_id.header_value()
        )
}
