TempFile

Struct TempFile 

Source
pub struct TempFile(/* private fields */);
Expand description

A temporary file.

A temporary file, generated with tempfile crate.

Methods from Deref<Target = NamedTempFile>§

Source

pub fn path(&self) -> &Path

Get the temporary file’s path.

§Security

Referring to a temporary file’s path may not be secure in all cases. Please read the security section on the top level documentation of this type for details.

§Examples
use tempfile::NamedTempFile;

let file = NamedTempFile::new()?;

println!("{:?}", file.path());
Source

pub fn as_file(&self) -> &F

Get a reference to the underlying file.

Source

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

Securely reopen the temporary file.

This function is useful when you need multiple independent handles to the same file. It’s perfectly fine to drop the original NamedTempFile while holding on to Files returned by this function; the Files will remain usable. However, they may not be nameable.

§Errors

If the file cannot be reopened, Err is returned.

§Security

Unlike File::open(my_temp_file.path()), NamedTempFile::reopen() guarantees that the re-opened file is the same file, even in the presence of pathological temporary file cleaners.

§Examples
use tempfile::NamedTempFile;

let file = NamedTempFile::new()?;

let another_handle = file.reopen()?;
