Struct CorsConfig 

#[non_exhaustive]
pub struct CorsConfig {
    pub origins: Vec<String>,
    pub expose_headers: Vec<String>,
    pub max_age_secs: Option<u64>,
    pub grpc_web: bool,
}

CORS configuration.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

origins: Vec<String>

Allowed origins. Empty = permissive (dev mode).

expose_headers: Vec<String>

Response headers a browser script may read on top of the ones the proxy always exposes (grpc-status, grpc-message, grpc-status-details-bin and the rate-limit headers): typically upstream metadata forwarded as a header, such as x-request-id.

max_age_secs: Option<u64>

How long a browser may cache a preflight answer, in seconds. Unset, the browser’s own default applies.

grpc_web: bool

Apply this policy to gRPC-Web calls that pass through to the upstream and to their preflights, so a browser gets one policy for both (on by default). Off only for an upstream that sets CORS on gRPC-Web itself: its preflights then reach the upstream as well.
