Struct fruity::foundation::NSRange

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

Describe a portion of a series, such as characters in a string or objects in an array.

Fields

location: NSUInteger

The start index (0 is the first, as in C arrays).

For type compatibility with the rest of the system, LONG_MAX is the maximum value you should use for location.

length: NSUInteger

The number of items in the range (can be 0).

For type compatibility with the rest of the system, LONG_MAX is the maximum value you should use for length.

Implementations

impl NSRange

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

Returns a range with the specified values.

This is equivalent to NSMakeRange.

pub fn from_range(range: Range<NSUInteger>) -> Self

Converts from a native Rust range.

This takes into account empty ranges with an end less than start.

pub fn from_nsstring(string: &NSString<'_>) -> Self

Returns a range from a textual representation.

See documentation.

pub fn is_empty(&self) -> bool

Returns true if self has zero length.

pub fn contains(&self, location: NSUInteger) -> bool

Returns true if location is in self.

This is equivalent to NSLocationInRange.

pub fn end(&self) -> NSUInteger

Returns the sum of the location and length of the range.

The result wraps on overflow.

This is equivalent to NSMaxRange.

pub fn to_nsstring(self) -> Arc<NSString<'static>>

Returns a string representation of self.

See documentation.

pub fn union(self, other: Self) -> Self

Returns a range covering all indices in and between self and other.

See documentation.

pub fn intersection(self, other: Self) -> Self

Returns a range covering all indices in and between self and other.

If the returned range’s length is 0, then the two ranges don’t intersect, and the value of location is undefined.

See documentation.

Trait Implementations
