Struct LocalFs 

pub struct LocalFs { /* private fields */ }

Local filesystem backend.

All operations are relative to root. For example, if root is /home/amy/project, then read("src/main.rs") reads /home/amy/project/src/main.rs.

Implementations

impl LocalFs

pub fn new(root: impl Into<PathBuf>) -> LocalFs

Create a new local filesystem rooted at the given path.

The path must exist and be a directory.

pub fn read_only(root: impl Into<PathBuf>) -> LocalFs

Create a read-only local filesystem.

pub fn set_read_only(&mut self, read_only: bool)

Set whether this filesystem is read-only.

pub fn root(&self) -> &Path

Get the root path.
