Trait Implementations

impl<V: Clone> Clone for DeviceLayer<V>

fn clone(&self) -> DeviceLayer<V>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<V: Debug> Debug for DeviceLayer<V>

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

Formats the value using the given formatter.

impl<V: VirtualFileSystem> VirtualFileSystem for DeviceLayer<V>

fn read_file(&mut self, path: &str) -> VfsResult<Vec<u8>>

fn read_dir(&mut self, path: &str) -> VfsResult<Vec<String>>

fn read_dir_limited( &mut self, path: &str, max_entries: usize, ) -> VfsResult<Vec<String>>

fn read_dir_with_types(&mut self, path: &str) -> VfsResult<Vec<VirtualDirEntry>>

fn write_file( &mut self, path: &str, content: impl Into<Vec<u8>>, ) -> VfsResult<()>

Writes caller-owned bytes into the filesystem.

fn create_file_exclusive( &mut self, path: &str, content: impl Into<Vec<u8>>, ) -> VfsResult<()>

fn append_file( &mut self, path: &str, content: impl Into<Vec<u8>>, ) -> VfsResult<u64>

Appends caller-owned bytes into the filesystem after checking that the in-memory file can grow without overflowing addressable memory.

fn create_dir(&mut self, path: &str) -> VfsResult<()>

fn mkdir(&mut self, path: &str, recursive: bool) -> VfsResult<()>

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

fn stat(&mut self, path: &str) -> VfsResult<VirtualStat>

fn remove_file(&mut self, path: &str) -> VfsResult<()>

fn remove_dir(&mut self, path: &str) -> VfsResult<()>

fn rename(&mut self, old_path: &str, new_path: &str) -> VfsResult<()>

fn realpath(&self, path: &str) -> VfsResult<String>

fn read_link(&self, path: &str) -> VfsResult<String>

fn lstat(&self, path: &str) -> VfsResult<VirtualStat>

fn link(&mut self, old_path: &str, new_path: &str) -> VfsResult<()>

fn truncate(&mut self, path: &str, length: u64) -> VfsResult<()>

Resizes a file. VM resource policy must be enforced by the caller.

fn pread( &mut self, path: &str, offset: u64, length: usize, ) -> VfsResult<Vec<u8>>

fn read_text_file(&mut self, path: &str) -> VfsResult<String>

fn pwrite( &mut self, path: &str, content: impl Into<Vec<u8>>, offset: u64, ) -> VfsResult<()>

Writes caller-owned bytes at an offset after checking that the in-memory file can grow without overflowing addressable memory.
