Trait Implementations

impl Drop for MountTable

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl VirtualFileSystem for MountTable

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

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

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

Writes caller-owned bytes into the filesystem.

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

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

fn create_dir_with_mode( &mut self, path: &str, mode: Option<u32>, ) -> Result<(), VfsError>

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

fn mkdir_with_mode( &mut self, path: &str, recursive: bool, mode: Option<u32>, ) -> Result<(), VfsError>

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

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

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

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