Enum RequestIdMode 

pub enum RequestIdMode {
    Permissive,
    Strict,
}

Request ID validation behavior for inbound x-request-id values.

Valid inbound IDs must parse as UUID v4 values. Invalid header syntax, non-UUID strings, and UUIDs from other versions are treated as malformed. Missing IDs are never rejected; the configured generator is used instead.

Variants

Permissive

Propagate valid UUID v4 IDs and replace malformed incoming IDs.

This mode is useful in development and at integration boundaries where clients may still send legacy IDs. A malformed inbound value is not exposed to handlers; it is replaced with a generated ID before the request reaches the inner service.

Strict

Propagate valid UUID v4 IDs and reject malformed incoming IDs.

A malformed inbound value returns 400 Bad Request with an invalid_request_id JSON error body. The rejection response still receives a generated request ID in the configured response header.

Trait Implementations

impl Clone for RequestIdMode

fn clone(&self) -> RequestIdMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RequestIdMode

impl Debug for RequestIdMode

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

Formats the value using the given formatter.

impl Eq for RequestIdMode

impl PartialEq for RequestIdMode

fn eq(&self, other: &RequestIdMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
