Struct MountableFS

pub struct MountableFS { /* private fields */ }

A filesystem that supports the mounting of other filesystems at designated paths (excluding the root).

Implementations

impl MountableFS

pub fn mount<P: AsRef<Path>>( &self, path: P, fs: Box<dyn FileSystem + Send + Sync>, ) -> Result<()>

Mounts a filesystem at the given path.

Arguments

path: The path to mount the filesystem at.
fs: The filesystem to mount.

Trait Implementations

impl Default for MountableFS

fn default() -> MountableFS

Returns the “default value” for a type.

impl FileSystem for MountableFS

fn create_dir(&self, _path: &str) -> Result<()>

Creates a directory at path.

fn metadata(&self, path: &str) -> Result<Metadata>

Returns the metadata for the file/folder at `path.

fn open_file_options( &self, path: &str, options: &OpenOptions, ) -> Result<Box<dyn File>>

Opens a file at path with options options.

fn read_dir( &self, path: &str, ) -> Result<Box<dyn Iterator<Item = Result<DirEntry>>>>

Lists the files and folders contained in the directory denoted by path.

fn remove_dir(&self, _path: &str) -> Result<()>

Removes the directory at path.

fn remove_file(&self, _path: &str) -> Result<()>

Removes a file at path.

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

Creates a directory path and all of its parents.

fn create_file(&self, path: &str) -> Result<Box<dyn File>>

Creates a file at path in write mode. The file will be opened in truncate mode, so all contents will be overwritten. If this is not desirable, use open_file directly.

fn exists(&self, path: &str) -> Result<bool>

Returns Ok(true) or Ok(false) if a file or folder at path does or does not exist, and Err(_) if the presence cannot be verified.

fn open_file(&self, path: &str) -> Result<Box<dyn File>>

Opens a file at path for reading.

impl<'a> FromIterator<(&'a str, Box<dyn FileSystem + Sync + Send>)> for MountableFS

fn from_iter<T: IntoIterator<Item = (&'a str, Box<dyn FileSystem + Send + Sync>)>>( iter: T, ) -> Self

Creates a value from an iterator.
