Struct OptionSet

pub struct OptionSet { /* private fields */ }

Set of the shell options and their states.

Implementations

impl OptionSet

pub fn empty() -> Self

Creates an option set with all options disabled.

pub fn get(&self, option: Option) -> State

Returns the current state of the option.

pub fn set(&mut self, option: Option, state: State)

Changes an option’s state.

Some options should not be changed after the shell startup, but that does not affect the behavior of this function.

TODO: What if an option that is mutually exclusive with another is set?

Trait Implementations

impl Clone for OptionSet

fn clone(&self) -> OptionSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptionSet

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

Formats the value using the given formatter.

impl Default for OptionSet

Defines the default option set.

Note that the default set is not empty. The following options are enabled by default: Clobber, Exec, Glob, Log, Unset

fn default() -> Self

Returns the “default value” for a type.

impl Extend<Option> for OptionSet

fn extend<T: IntoIterator<Item = Option>>(&mut self, iter: T)

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

Reserves capacity in a collection for the given number of additional elements.

impl Hash for OptionSet

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 OptionSet

fn eq(&self, other: &OptionSet) -> 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.
