Builder-style methods for Command that take self and return Self.

Required Methods

fn with_current_dir(self, dir: impl AsRef<Path>) -> Self

Sets the working directory.

Corresponds to Command::current_dir.

fn with_env(self, key: impl AsRef<OsStr>, value: impl AsRef<OsStr>) -> Self

Sets an environment variable.

Corresponds to Command::env.

fn without_env(self, key: impl AsRef<OsStr>) -> Self

Removes an environment variable.

Corresponds to Command::env_remove.

fn with_no_env(self) -> Self

Clears all environment variables.

Corresponds to Command::env_clear.

fn with_arg(self, arg: impl AsRef<OsStr>) -> Self

Adds one argument.

Corresponds to Command::arg.

fn with_stdin(self, stdio: Stdio) -> Self

Configures stdin.

Corresponds to Command::stdin.

fn with_stdout(self, stdio: Stdio) -> Self

Configures stdout.

Corresponds to Command::stdout.

fn with_stderr(self, stdio: Stdio) -> Self

Configures stderr.

Corresponds to Command::stderr.

Provided Methods

fn with_args<Args>(self, args: Args) -> Self

where Args: IntoIterator, Args::Item: AsRef<OsStr>,

Adds multiple arguments.

Corresponds to Command::args.

fn with_envs<Envs, Key, Value>(self, envs: Envs) -> Self

where Envs: IntoIterator<Item = (Key, Value)>, Key: AsRef<OsStr>, Value: AsRef<OsStr>,

Sets multiple environment variables.

Corresponds to Command::envs.

fn without_envs<Keys>(self, keys: Keys) -> Self

where Keys: IntoIterator, Keys::Item: AsRef<OsStr>,

Removes multiple environment variables.

Equivalent to repeated Command::env_remove; no direct inherent method.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
