Enum EntryPredicate 

#[non_exhaustive]
pub enum EntryPredicate {
    QueryByExample(QueryByExample),
}

What a request asks of each entry.

Deliberately an enum with a single variant today. The variant is the settled v1 predicate; the enum is the seam that lets a later predicate family – an expression tree, say – be added without replacing the request API that carries it.

Variants (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.

QueryByExample(QueryByExample)

A flat conjunction of query-by-example clauses.

Implementations

impl EntryPredicate

pub fn matches(&self, entry: &DirectoryEntry) -> bool

Whether entry satisfies this predicate.

pub fn matches_everything(&self) -> bool

Whether this predicate accepts every entry, so evaluation can be skipped entirely.
