Struct objc2_foundation::NSRange

#[repr(C)]
pub struct NSRange {
    pub location: NSUInteger,
    pub length: NSUInteger,
}

Available on crate feature NSRange only.

TODO.

See Apple’s documentation.

Fields

location: NSUInteger

The lower bound of the range (inclusive).

length: NSUInteger

The number of items in the range, starting from location.

Implementations

impl NSRange

pub const fn new(location: usize, length: usize) -> Self

Create a new range with the given values.

Examples

use objc2_foundation::NSRange;
assert_eq!(NSRange::new(3, 2), NSRange::from(3..5));

pub fn is_empty(&self) -> bool

Returns true if the range contains no items.

Examples

use objc2_foundation::NSRange;

assert!(!NSRange::from(3..5).is_empty());
assert!( NSRange::from(3..3).is_empty());

pub fn contains(&self, index: usize) -> bool

Returns true if the index is within the range.

Examples

use objc2_foundation::NSRange;

assert!(!NSRange::from(3..5).contains(2));
assert!( NSRange::from(3..5).contains(3));
assert!( NSRange::from(3..5).contains(4));
assert!(!NSRange::from(3..5).contains(5));

assert!(!NSRange::from(3..3).contains(3));

pub fn end(&self) -> usize

Returns the upper bound of the range (exclusive).

Trait Implementations

impl Clone for NSRange

fn clone(&self) -> NSRange

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NSRange

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

Formats the value using the given formatter.

impl Default for NSRange

fn default() -> NSRange

Returns the “default value” for a type.

impl Encode for NSRange

const ENCODING: Encoding = _

The Objective-C type-encoding for this type.

impl From<NSRange> for Range<usize>

fn from(nsrange: NSRange) -> Self

Converts to this type from the input type.

impl From<Range<usize>> for NSRange

fn from(range: Range<usize>) -> Self

Converts to this type from the input type.

impl Hash for NSRange

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 Ord for NSRange

fn cmp(&self, other: &NSRange) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for NSRange

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for NSRange

fn partial_cmp(&self, other: &NSRange) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl RefEncode for NSRange

const ENCODING_REF: Encoding = _

The Objective-C type-encoding for a reference of this type.

impl Copy for NSRange

impl Eq for NSRange

impl StructuralPartialEq for NSRange
