UnverifiedAuthPolicy

cratestack::ratelimit

Enum UnverifiedAuthPolicy 

Source 
#[non_exhaustive]
pub enum UnverifiedAuthPolicy {
    Budget,
    Ignore,
}
Expand description

What to do with an Authorization header that nothing has verified — which is every Authorization header this layer sees, since it runs before authentication.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Budget

Key on the (hashed) header as before, but subject to a BucketBudget that caps how many distinct buckets one scope may mint. Preserves per-caller throttling for real callers (cratestack#416) while bounding the keyspace an attacker can create. The default.

§

Ignore

Ignore the header entirely and key on the verified peer address. Strictly stronger against amplification — nothing caller-supplied enters the key at all — at the cost of collapsing every caller behind one NAT/proxy egress into one bucket. Choose it when the limiter is a security control and callers are known to be per-address.

painted.fg(Color::White);

Set foreground color to white using white().

§

fn quirk(&self, value: Quirk) -> Painted<&T>
