Struct CachingHelper 

pub struct CachingHelper { /* private fields */ }

Process-local credential cache, keyed on the full Query tuple.

Populated by Helper::approve and consulted on Helper::fill; Helper::reject drops the corresponding entry. Lives for one CLI invocation; a long-running daemon would want a TTL layered on top.

Implementations

impl CachingHelper

pub fn new() -> Self

Create an empty cache.

Trait Implementations

impl Debug for CachingHelper

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CachingHelper

fn default() -> CachingHelper

Returns the “default value” for a type.

impl Helper for CachingHelper

fn approve(&self, query: &Query, creds: &Credentials) -> Result<(), HelperError>

Cache the working credentials so the next request skips the helper chain entirely.

fn reject(&self, query: &Query, _creds: &Credentials) -> Result<(), HelperError>

Drop the cached entry — whatever’s in there clearly didn’t work.

fn fill(&self, query: &Query) -> Result<Option<Credentials>, HelperError>

Try to fetch credentials for query.
