pub struct File {
    inner: NamedTempFile,
    path: PathBuf,
}

A unique temporary file removed when dropped.

Fields

inner: NamedTempFile

path: PathBuf

Implementations

impl File

pub fn with_affixes(prefix: &str, suffix: &str) -> Result<Self>

Create a unique temporary file with diagnostic filename affixes.

The file is removed when this guard is dropped. Call Self::retain to preserve it as a regular open file.

Errors

Returns a contextual error when the file cannot be created.

pub fn path(&self) -> &Path

Return the temporary file’s unique path.

pub fn retain(self) -> Result<File>

Retain the file after this temporary guard is consumed.

The returned open file owns its custom path context. Dropping that handle does not remove the filesystem entry. Its caller is responsible for eventual deletion.

Errors

Returns a contextual error when the platform cannot retain the file.
