Struct LowerBound 

pub struct LowerBound<T>(/* private fields */);

Lower bound of a range.

Specialization of Bound where comparisons make sense in all contexts.

Implementations

impl<T> LowerBound<T>

pub fn excluded(t: T) -> Self

Constructs a new excluded lower bound.

Example

use rangetools::LowerBound;

let b1 = LowerBound::excluded(2);
let b2 = LowerBound::excluded(3);
assert!(b1 < b2);

pub fn included(t: T) -> Self

Constructs a new included lower bound.

Example

use rangetools::{LowerBound, LowerBoundedRange};

let b = LowerBound::included(2);
let r= LowerBoundedRange::from(2..);
assert_eq!(b, r.start);

pub fn to_bound(self) -> Bound<T>

where T: Copy,

Get the inner bound value.

Be careful when performing operations on raw bounds, as they can have different meanings depending on their original context.

pub fn map<U, F>(self, f: F) -> LowerBound<U>

where F: FnOnce(T) -> U,

Maps a LowerBound<T> to a LowerBound<U> by applying a function to the contained value.

Example

use rangetools::LowerBound;

let b1 = LowerBound::included(3);
let b2 = b1.map(|n| n + 1);
assert_eq!(b2, LowerBound::included(4));
