Enum Boundary 

pub enum Boundary {
    Root,
    Marker(&'static str),
}

Controls where an Ancestors walk stops.

The walk always starts at the current working directory and moves toward the filesystem root. The boundary determines where it ends.

Variants

Root

Walk all the way to the filesystem root.

Marker(&'static str)

Walk until a directory is found that contains the named file or subdirectory (e.g. ".git", "Cargo.toml").

The directory containing the marker is included in the search — it is typically the project root and a natural place for config files. If the marker is never found, the walk continues to the filesystem root.

Trait Implementations

impl Clone for Boundary

fn clone(&self) -> Boundary

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Boundary

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

Formats the value using the given formatter.

impl PartialEq for Boundary

fn eq(&self, other: &Boundary) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
