Filesystem seam used by atomic replacement and Windows quarantine.

Required Methods

fn exists(&self, path: &Path) -> bool

Whether a path exists.

fn rename(&self, from: &Path, to: &Path) -> Result<()>

Rename a path atomically within a filesystem.

Errors

Propagates the underlying std::io error when the rename fails.

fn copy(&self, from: &Path, to: &Path) -> Result<u64>

Copy a file.

Errors

Propagates the underlying std::io error when the copy fails.

fn remove_file(&self, path: &Path) -> Result<()>

Remove a file if present.

Errors

Propagates the underlying std::io error when the removal fails.

fn remove_dir_all(&self, path: &Path) -> Result<()>

Recursively remove a directory if present.

Errors

Propagates the underlying std::io error when the removal fails.

fn create_dir_all(&self, path: &Path) -> Result<()>

Recursively create a directory.

Errors

Propagates the underlying std::io error when creation fails.

fn permissions(&self, path: &Path) -> Result<Permissions>

Read file permissions.

Errors

Propagates the underlying std::io error when metadata read fails.

fn set_permissions(&self, path: &Path, permissions: Permissions) -> Result<()>

Set file permissions.

Errors

Propagates the underlying std::io error when setting permissions fails.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
