Struct CorsConfig 

pub struct CorsConfig {
    pub allow_origins: Vec<String>,
    pub allow_all_origins: bool,
    pub credentials: bool,
}

Cross-Origin Resource Sharing (CORS) configuration for an HTTP server.

Controls which origins are allowed to make cross-origin requests, whether credentials are included in responses, and generates appropriate CORS headers.

Instantiated via CorsConfigBuilder to ensure the unsafe credentialed-wildcard combination cannot be represented.

Fields

allow_origins: Vec<String>

List of origins allowed to access the server (may contain "*").

allow_all_origins: bool

Whether all origins ("*") are allowed.

credentials: bool

Whether credentials (Authorization, cookies, etc.) are included in responses.

Implementations

impl CorsConfig

pub fn preflight_response( &self, req_origin: Option<&str>, ) -> Response<ResponseBody>

Build a CORS preflight response (HTTP 204).

Called for OPTIONS requests. Returns appropriate CORS headers based on the request’s Origin header and this config’s allowed origins.

pub fn apply_to_response( &self, resp: &mut Response<ResponseBody>, req_origin: Option<&str>, )

Apply CORS headers to a response based on the request’s Origin header.

Called after a handler completes successfully. Mutates the response to add appropriate Access-Control-* headers.
