Trait StartsWith 

Source 
pub trait StartsWith<Prefix: ?Sized> {

    fn starts_with_exactly(&self, prefix: &Prefix) -> bool;
}
Expand description

This trait abstracts over the concept of matching a prefix pattern against a path

To understand the semantics of how a given prefix pattern matches against a path, you must check the implementation for the type, but all of the provided implementations are broken down into two categories:

  1. The prefix is a Path or PathBuf, in which case each component of the prefix is matched against each component of self until the entire prefix has been visited, or a mismatch is identified.
  2. The prefix is a str or something that derefs to str, in which case the prefix is matched against the first component of self (which component of self is considered “first” is dependent on whether the match must be exact or not).

Required Methods§

Source

fn starts_with(&self, prefix: &Prefix) -> bool

Returns true if the current path, sans root component, starts with prefix

Source

fn starts_with_exactly(&self, prefix: &Prefix) -> bool

Returns true if the current path, including root component, starts with prefix
