Required Methods§
Provided Methods§
sourcefn flat_map<G, H, O2>(self, g: G) -> FlatMap<Self, G, O>
fn flat_map<G, H, O2>(self, g: G) -> FlatMap<Self, G, O>
Creates a second parser from the output of the first one, then apply over the rest of the input
sourcefn and_then<G, O2>(self, g: G) -> AndThen<Self, G, O>
fn and_then<G, O2>(self, g: G) -> AndThen<Self, G, O>
Applies a second parser over the output of the first one
sourcefn and<G, O2>(self, g: G) -> And<Self, G>
fn and<G, O2>(self, g: G) -> And<Self, G>
Applies a second parser after the first one, return their results as a tuple
