Struct Scratch 

pub struct Scratch { /* private fields */ }

A scratch path that goes away when this value does.

Dropping it removes the path, so a tool that fails part-way leaves nothing behind and no caller has to remember an error path.

let scratch = concinnity_host::scratch::Scratch::file("notes.txt");
std::fs::write(scratch.path(), b"working").unwrap();
let path = scratch.path().to_path_buf();
drop(scratch);
assert!(!path.exists());

Implementations

impl Scratch

pub fn file(name: &str) -> Self

A file path, unique to this call. Nothing is written yet.

pub fn dir(name: &str) -> Result<Self>

A directory, unique to this call and created empty.

Errors

If the directory cannot be created.

pub fn path(&self) -> &Path

The path itself.

Trait Implementations

impl Drop for Scratch

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.
