Struct And 

pub struct And<L, R> { /* private fields */ }

Requires both predicates to return Cacheable.

Short-circuits: if the left predicate returns NonCacheable, the right predicate is not evaluated.

Implementations

impl<L, R> And<L, R>

pub fn new(left: L, right: R) -> And<L, R>

Creates a new And combinator from two predicates.

Trait Implementations

impl<L, R> Debug for And<L, R>

where L: Debug, R: Debug,

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

Formats the value using the given formatter.

impl<L, R> Predicate for And<L, R>

where L: Predicate + Send + Sync, R: Predicate<Subject = <L as Predicate>::Subject> + Send + Sync, <L as Predicate>::Subject: Send,

type Subject = <L as Predicate>::Subject

The type being evaluated by this predicate.

fn check<'life0, 'async_trait>( &'life0 self, subject: <And<L, R> as Predicate>::Subject, ) -> Pin<Box<dyn Future<Output = PredicateResult<<And<L, R> as Predicate>::Subject>> + Send + 'async_trait>>

where 'life0: 'async_trait, And<L, R>: 'async_trait,

Evaluate whether the subject should be cached.
