Struct fencryption_lib::tmp::TmpDir

pub struct TmpDir(_);

TmpDir is a struct to manipulate a temporary directory.

The “path” argument (in some methods) must be relative because it will be joined to the temporary directory path.

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

Implementations

impl TmpDir

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

pub fn path(&self) -> &PathBuf

pub fn unique_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 temporary directory. See fs::write.

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

Reads a file in the temporary directory. See fs::read.

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

Creates a directory inside the temporary directory. See 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 (inside the temporary directory). See fs::create_dir_all.

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

Creates a file in the temporary directory. See File::create.

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

Opens a file in the temporary directory. See File::open.

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

Opens a file in the temporary directory using the provided OpenOptions. See fs::OpenOptions::open.

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

Gets metadata for the given path. Akin to fs::metadata.

pub fn exists<P>(&self, path: P) -> boolwhere
    P: AsRef<Path>,

Checks if a path exists in the current directory. Akin to Path::exists.

pub fn read_dir(&self) -> Result<ReadDir>

Reads temporary directory. Akin to fs::read_dir.

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.
