Struct fencryption_lib::tmp_dir::TmpDir

pub struct TmpDir(_);

TmpDir is a struct to manipulate a temporary directory.

The path argument in method that have it must be relative because it will be joined to the temporary directory path.

When this struct is dropped, the temporary directory is automatically deleted.

Implementations

impl TmpDir

pub fn new() -> Result<TmpDir, Error>

pub fn path(&self) -> PathBuf

pub fn gen_path(&self) -> PathBuf

Generates a new unique path in the temporary directory.

pub fn write_file<P, C>(&self, path: P, contents: C) -> Result<()>where
    P: AsRef<Path>,
    C: AsRef<[u8]>,

Writes to a file (or create it if it doesn’t exist) in the TmpDir. See std::fs::write.

pub fn read_file<P>(&self, path: P) -> Result<Vec<u8>>where
    P: AsRef<Path>,

Reads a file from the TmpDir. See std::fs::read.

pub fn create_dir<P>(&self, path: P) -> Result<()>where
    P: AsRef<Path>,

Creates a directory. See std::fs::create_dir.

pub fn create_dir_all<P>(&self, path: P) -> Result<()>where
    P: AsRef<Path>,

Creates a directory and all of its parent if they are missing. See std::fs::create_dir_all.

pub fn create_file<P>(&self, path: P) -> Result<File>where
    P: AsRef<Path>,

Creates a file in the TmpDir. See std::fs::File::create.

pub fn open_file<P>(&self, path: P) -> Result<File>where
    P: AsRef<Path>,

Opens a file from the TmpDir. See std::fs::File::open.

pub fn open_file_with_opts<P>(&self, opts: OpenOptions, path: P) -> Result<File>where
    P: AsRef<Path>,

Opens a file from the TmpDir using the provided OpenOptions. See std::fs::OpenOptions::open.

Trait Implementations

impl Drop for TmpDir

Impl Drop trait so when the TmpDir is dropped, the directory is deleted.

fn drop(&mut self)

Executes the destructor for this type.
