Struct Filters 

pub struct Filters<'a> {
    pub kind: Option<Kind>,
    pub parent: Option<&'a str>,
    pub returns: Option<&'a str>,
}

Which records a search may consider, independent of the query itself: a kind, an enclosing type, a return type. Grouped so every search path takes one argument, and so adding a filter doesn’t ripple through six signatures.

Fields

kind: Option<Kind>

Only this kind of entity (-k).

parent: Option<&'a str>

Only members of this enclosing type (a resolved Type.field qualifier).

returns: Option<&'a str>

Only fields whose type is this, wrappers peeled (--returns). Wildcards allowed; a plain name is an exact, case-insensitive match.

Implementations

impl Filters<'_>

pub fn compile(&self) -> Predicate<'_>

Compile once, then test many records — this is where the returns pattern gets parsed, rather than per record.

Trait Implementations

impl<'a> Clone for Filters<'a>

fn clone(&self) -> Filters<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Copy for Filters<'a>

impl<'a> Default for Filters<'a>

fn default() -> Filters<'a>

Returns the “default value” for a type.
