Struct tux::TempDir

pub struct TempDir { /* private fields */ }

Manages a temporary directory that can be used by tests. Supports creating files in the directory. Once the value is dropped the entire directory and its contents are deleted.

Examples

use tux::temp_dir;

let dir = temp_dir();
dir.create_file("test.txt", "some content");
println!("{:?}", dir.path());
println!("{}", dir.path_str());

// this will delete the directory and its contents
drop(dir);

Implementations

impl TempDir

pub fn create_new() -> TempDir

Creates a new instance. For convenience, use the alias temp_dir.

pub fn path(&self) -> &Path

Absolute path to the temporary directory.

pub fn path_str(&self) -> &str

Absolute path to the temporary directory as a plain string.

pub fn create_file<S: AsRef<[u8]>>(&self, name: &str, contents: S) -> PathBuf

Creates a file in the temporary directory. Returns the absolute path to the created file.

The file name can contain path components for intermediate directories, and those will be created as necessary.

Errors

• This will panic if attempting to create files outside the temporary directory.
• This will panic if the file creation or writing fails.

pub fn run_bin(&self, cmd: &str, args: &[&str]) -> String

Equivalent to run_bin but runs the binary with the temporary directory set as current working directory.

To get the entire process output, including the exit code and error output, use get_bin_output instead.

pub fn get_bin_output(&self, cmd: &str, args: &[&str]) -> Output

Similar to run_bin but returns the entire process output. Use this to access the exit code and error output.
