Struct ExtensionRoleExtractor 

pub struct ExtensionRoleExtractor<T> { /* private fields */ }

Extract roles from a request extension.

This extractor looks for roles that were set by a previous middleware (e.g., an authentication middleware) as a request extension.

Example

use axum_acl::ExtensionRoleExtractor;

// The authentication middleware should insert a Roles struct into extensions
#[derive(Clone)]
struct UserRoles(u32);

let extractor = ExtensionRoleExtractor::<UserRoles>::new(|roles| roles.0);

Implementations

impl<T> ExtensionRoleExtractor<T>

pub fn new<F>(extract_fn: F) -> Self

where F: Fn(&T) -> u32 + Send + Sync + 'static,

Create a new extension role extractor.

The extract_fn converts the extension type to a roles bitmask.
