Securely create and manage temporary files. Temporary files created by this create are automatically deleted.
This crate provides two temporary file variants:
NamedTempFile. When choosing
between the variants, prefer
TempFile unless you either need to know the file's path or to be
able to persist it.
TempFile will (almost) never fail to cleanup temporary files but
NamedTempFile will if its
destructor doesn't run. This is because
TempFile relies on the OS to cleanup the underlying
file so the file while
NamedTempFile relies on its destructor to do so.
In the presence of pathological temporary file cleaner, relying on file paths is unsafe because a temporary file cleaner could delete the temporary file which an attacker could then replace.
TempFile doesn't rely on file paths so this isn't an issue. However,
rely on file paths.
A named temporary file.
An unnamed temporary file.
