Struct OptionalSecurityContext 

pub struct OptionalSecurityContext(pub Option<SecurityContext>);

Extractor for optional SecurityContext from authenticated user and headers.

When used in a handler, automatically extracts:

1. AuthUser from request extensions (if present)
2. Request metadata from HTTP headers (request ID, IP, tenant ID)
3. Creates SecurityContext from both

If authentication is not present, returns None (optional extraction).

Example

// Requires: running Axum server with authentication middleware configured.
async fn graphql_handler(
    State(state): State<AppState>,
    OptionalSecurityContext(context): OptionalSecurityContext,
) -> Result<Response> {
    // context is Option<SecurityContext>
}

Trait Implementations

impl Clone for OptionalSecurityContext

fn clone(&self) -> OptionalSecurityContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptionalSecurityContext

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

Formats the value using the given formatter.

impl<S> FromRequestParts<S> for OptionalSecurityContext

where S: Send + Sync + 'static,

type Rejection = ExtensionRejection

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

fn from_request_parts( parts: &mut Parts, _state: &S, ) -> impl Future<Output = Result<Self, Self::Rejection>> + Send

Perform the extraction.
