Required Associated Types

type File: FileExt

type TempFile: FileExt

type Rng: Rng

Required Methods

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

fn open( &self, create_new: bool, read: bool, write: bool, path: &Path, ) -> Result<Self::File>

TODO: when adding an async variant make sure all places where async is needed are replaced

fn tempfile(&self) -> Result<Self::TempFile>

fn now(&self) -> DateTime<Utc>

fn hard_link(&self, src: &Path, dst: &Path) -> Result<()>

fn with_rng<F, R>(&self, f: F) -> R

where F: FnOnce(&mut Self::Rng) -> R,

fn remove_file_async( &self, path: &Path, ) -> impl Future<Output = Result<()>> + Send

Provided Methods

fn uuid(&self) -> Uuid

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
