pub enum Selection {
    All,
    Some(Vec<SomeElementType>),
    None,
}

A parsed selection. Can represent all, none, or some set of ranges and items.

All elements are in the selected set

Some(Vec<SomeElementType>)

Some elements are in the selected set. The list of selections are in the Vec.

Implementations

impl Selection

pub fn contains_item(&self, item: usize) -> bool

Check if the selection contains an item. Returns true if All, false if None, and checks included elements if Some.

Trait Implementations

impl Debug for Selection

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

Formats the value using the given formatter.

impl FromStr for Selection

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for Selection

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

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

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

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