Struct vmm_sys_util::tempfile::TempFile

pub struct TempFile { /* fields omitted */ }

Wrapper for working with temporary files.

The file will be maintained for the lifetime of the TempFile object.

Methods

impl TempFile

pub fn new_with_prefix<P: AsRef<OsStr>>(prefix: P) -> Result<TempFile>

Creates the TempFile using a prefix.

Arguments

prefix: The path and filename where to creat the temporary file. Six random alphanumeric characters will be added to the end of this to form the filename.

pub fn new_in(path: &Path) -> Result<Self>

Creates the TempFile inside a specific location.

Arguments

path: The path where to create a temporary file with a filename formed from six random alphanumeric characters.

pub fn new() -> Result<Self>

Creates the TempFile.

Creates a temporary file inside $TMPDIR if set, otherwise inside /tmp. The filename will consist from six random alphanumeric characters.

pub fn remove(&mut self) -> Result<()>

Removes the temporary file.

Calling this is optional as dropping a TempFile object will also remove the file. Calling remove explicitly allows for better error handling.

pub fn as_path(&self) -> &Path

Returns the path to the tempfile if it is currently valid

pub fn as_file(&self) -> &File

Returns a reference to the File
