JwtCache

Struct JwtCache 

Source
pub struct JwtCache { /* private fields */ }
Expand description

A bounded cache of validated tokens.

Implementations§

Source§

impl JwtCache

Source

pub fn new(enabled: bool, max_lifetime_secs: u64) -> Option<Self>

Build a cache, or None if the configuration turns it off.

A zero lifetime disables it, as in PostgREST – an entry that expires the moment it is written is only overhead.

Source

pub fn clear(&self)

Forget every token held.

Done by the cache itself whenever the key set it is used with changes; for a host that wants to revoke for some other reason.

Source

pub fn stats(&self) -> CacheStats

The lookups answered so far, for a host to export as a metric.

Source

pub fn authenticate( &self, auth_header: Option<&str>, config: &JwtConfig, ) -> Result<AuthResult, JwtError>

Authenticate, consulting the cache.

Falls through to crate::authenticate for anything not cacheable: a request with no token at all, and a token already at or past its own expiry.

Source

pub fn authenticate_with_outcome( &self, auth_header: Option<&str>, config: &JwtConfig, ) -> (Result<AuthResult, JwtError>, CacheOutcome)

authenticate, saying whether the cache answered.

A separate method rather than a change to that one’s return type, so that every caller of it builds unchanged. The verdict is the same either way; the outcome is for a span or a metric to record.
