Struct ScratchFile 

pub struct ScratchFile { /* private fields */ }

RAII-cleaned scratch file anchored under the ZLayer data dir’s tmp/. Drop removes the file.

Implementations

impl ScratchFile

pub fn from_named(inner: NamedTempFile) -> Self

Wrap an existing tempfile::NamedTempFile. Prefer [zlayer_paths::ZLayerDirs::scratch_file] over calling this directly.

pub fn path(&self) -> &Path

Path of the scratch file on disk.

pub fn as_file(&self) -> &File

Read-only reference to the underlying file handle.

pub fn as_file_mut(&mut self) -> &mut File

Mutable reference to the underlying file handle.

pub fn reopen(&self) -> Result<File>

Open a fresh handle to the same on-disk file.

Errors

Returns the underlying filesystem error if opening fails.

pub fn persist(self, dest: impl AsRef<Path>) -> Result<File, PersistError>

Persist the file to a permanent location, consuming the guard.

Errors

Returns the underlying tempfile::PersistError if the rename fails.

pub fn into_temp_path(self) -> TempPath

Consume the guard and return the underlying TempPath (still RAII-cleaned, but without an open file handle).

Trait Implementations

impl AsRef<Path> for ScratchFile

fn as_ref(&self) -> &Path

Converts this type into a shared reference of the (usually inferred) input type.

impl Debug for ScratchFile

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
