Struct Filter 

pub struct Filter<V = Val>(/* private fields */);

Function from a value to a stream of value results.

Trait Implementations

impl<V: Clone> Clone for Owned<V>

fn clone(&self) -> Owned<V>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<V: Debug> Debug for Owned<V>

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

Formats the value using the given formatter.

impl<V> Default for Owned<V>

fn default() -> Self

Returns the “default value” for a type.

impl<'a, V: ValT> FilterT<'a, V> for &'a Owned<V>

fn run( self, cv: (Ctx<'a, V>, V), ) -> Box<dyn Iterator<Item = Result<V, Error<V>>> + 'a>

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

fn update( self, cv: (Ctx<'a, V>, V), f: Box<dyn Update<'a, V> + 'a>, ) -> Box<dyn Iterator<Item = Result<V, Error<V>>> + '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, V>, V), f: F) -> Results<'a, T, Error<V>>

where F: Fn((Ctx<'a, V>, V), V) -> Results<'a, T, Error<V>> + '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, V>, V), ) -> Box<dyn Iterator<Item = (Result<V, Error<V>>, Result<V, Error<V>>)> + 'a>

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

fn cartesian3( self, m: Self, r: Self, cv: (Ctx<'a, V>, V), ) -> Box<dyn Iterator<Item = (Result<V, Error<V>>, Result<V, Error<V>>, Result<V, Error<V>>)> + 'a>

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

fn recurse( self, inner: bool, outer: bool, cv: (Ctx<'a, V>, V), ) -> Box<dyn Iterator<Item = Result<V, Error<V>>> + '_>

👎Deprecated since 1.2.0

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

fn recurse_update( self, cv: (Ctx<'a, V>, V), f: Box<dyn Update<'a, V> + 'a>, ) -> Box<dyn Iterator<Item = Result<V, Error<V>>> + 'a>

👎Deprecated since 1.2.0

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