Struct ValidSignature 

pub struct ValidSignature;

Proof that the request’s URL was signed by signed_url and hasn’t expired. A route that takes it answers 403 to any other URL.

As Option<ValidSignature> it never refuses, so one route can accept a signed link (a guest coming back from a mail or a payment page) or a logged-in user:

use renox::signed::ValidSignature;

async fn receipt(
    signature: Option<ValidSignature>,
    user: Option<AuthUser>,
    Path(order): Path<i64>,
) -> Result<String> {
    if signature.is_none() && user.is_none() {
        return Err(Error::Forbidden);
    }
    Ok(format!("Order {order}"))
}

(A logged-in user still needs a check that the order is theirs.)

Trait Implementations

impl<S: Send + Sync> FromRequestParts<S> for ValidSignature

type Rejection = Error

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

async fn from_request_parts(parts: &mut Parts, _: &S) -> Result<Self>

Perform the extraction.

impl<S: Send + Sync> OptionalFromRequestParts<S> for ValidSignature

type Rejection = Error

If the extractor fails, it will use this “rejection” type.

async fn from_request_parts(parts: &mut Parts, _: &S) -> Result<Option<Self>>

Perform the extraction.
