Enum Command 

pub enum Command {
    Show {
        symbolic: bool,
    },
    Set(Vec<Clause>),
}

Interpretation of command-line arguments that determine the behavior of the umask built-in

Variants

Show

Show the current file mode creation mask

Fields

symbolic: bool

Set(Vec<Clause>)

Set the file mode creation mask

Implementations

impl Command

pub fn set_from_raw_mask(mask: u16) -> Self

Creates a Command::Set variant from a raw mask.

This is a convenience method for creating a Command::Set variant from a raw mask. The result contains a single clause that sets the mask to the given value for all bits.

pub fn execute<S: Umask>(&self, env: &mut Env<S>) -> String

Executes the umask built-in.

Regardless of the command type, this function performs the following steps:

1. Obtain the current mask from the environment. (Umask::umask)
2. Compute a new mask to be set. (eval::new_mask)
3. Set the new mask. (Umask::umask)

Returns the string that should be printed to the standard output.

Trait Implementations

impl Clone for Command

fn clone(&self) -> Command

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Command

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Command

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Command

fn eq(&self, other: &Command) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
