Struct TestTempDirGuard

pub struct TestTempDirGuard<'d, T> {
    pub(crate) thing: T,
    pub(crate) tempdir: PhantomData<&'d ()>,
}

A T which relies on some temporary directory with lifetime d

Obtained from TestTempDir::used_by.

Using this type means that the T won’t outlive the temporary directory. (Typically, if it were to, things would malfunction. There might even be security hazards!)

Fields

thing: T

The thing

tempdir: PhantomData<&'d ()>

Placate the compiler

We use a notional () since we don’t want the compiler to infer drop glue.

Implementations

impl<'d, T> TestTempDirGuard<'d, T>

pub fn into_untracked(self) -> T

Obtain the inner T

It is up to you to ensure that T doesn’t outlive the temp directory used to create it.

pub fn with_path(thing: T, _path: &'d Path) -> Self

Create from a T and a &Path with the right lifetime

pub fn new_untracked(thing: T) -> Self

Create from a raw T

The returned lifetime is unfounded! It is up to you to ensure that the inferred lifetime is correct!
