Struct daggy::walker::SkipWhile

pub struct SkipWhile<G, W, P> { /* fields omitted */ }

A walker that invokes the predicate on elements until it returns false.

Once the predicate returns false, that element and all further elements are yielded.

Implementations

impl<G, W, P> SkipWhile<G, W, P>

pub fn new(walker: W, predicate: P) -> Self where
    G: GraphRef,
    W: Walker<G>,
    P: FnMut(G, &W::Item) -> bool, 

Create a new SkipWhile walker.
