pub struct Filter(/* private fields */);

Function from a value to a stream of value results.

Trait Implementations

impl Clone for Owned

fn clone(&self) -> Owned

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Owned

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

Formats the value using the given formatter.

impl Default for Owned

fn default() -> Owned

Returns the “default value” for a type.

impl<'a> FilterT<'a> for &'a Owned

fn run(self, cv: (Ctx<'a>, Val)) -> ValRs<'a>

f.run((c, v)) returns the output of v | f in the context c.

fn update(self, cv: (Ctx<'a>, Val), f: Box<dyn Update<'a> + 'a>) -> ValRs<'a>

p.update((c, v), f) returns the output of v | p |= f in the context c.

fn pipe<T: 'a, F>(self, cv: (Ctx<'a>, Val), f: F) -> Results<'a, T, Error>where F: Fn((Ctx<'a>, Val), Val) -> Results<'a, T, Error> + 'a,

For every value v returned by self.run(cv), call f(cv, v) and return all results.

fn cartesian( self, r: Self, cv: (Ctx<'a>, Val) ) -> Box<dyn Iterator<Item = (ValR, ValR)> + 'a>

Run self and r and return the cartesian product of their outputs.

fn recurse(self, inner: bool, outer: bool, cv: (Ctx<'a>, Val)) -> ValRs<'_>

Return the output of recurse(f) if inner and outer are true.

fn recurse_update( self, cv: (Ctx<'a>, Val), f: Box<dyn Update<'a> + 'a> ) -> ValRs<'a>

Return the output of recurse(l) |= f.
