impl<T> HasBranchesAPI for T

source§

fn branches_impl2<T>(self) -> impl Iterator<Item = T>
where Self: HasBranches<T> + Sized,

This is used internally. Should use branches instead.

fn get_impl<T>(self, segment: impl Into<String>) -> Option<T>
where Self: HasBranches<T> + Sized, T: HasPathSegment,

Gets a branch by its path segment. It’s discouraged to use this method directly. Instead, use the get and get_mut method from the HasGetAPI trait.
