Struct geng_core::prelude::Range

pub struct Range<Idx> {
    pub start: Idx,
    pub end: Idx,
}

The Range start..end contains all values with x >= start and x < end. It is empty unless start < end.

Examples

assert_eq!((3..5), std::ops::Range { start: 3, end: 5 });
assert_eq!(3 + 4 + 5, (3..6).sum());

let arr = [0, 1, 2, 3, 4];
assert_eq!(arr[ ..  ], [0,1,2,3,4]);
assert_eq!(arr[ .. 3], [0,1,2    ]);
assert_eq!(arr[ ..=3], [0,1,2,3  ]);
assert_eq!(arr[1..  ], [  1,2,3,4]);
assert_eq!(arr[1.. 3], [  1,2    ]);  // Range
assert_eq!(arr[1..=3], [  1,2,3  ]);

Fields

start: Idx

The lower bound of the range (inclusive).

end: Idx

The upper bound of the range (exclusive).

Implements substring slicing with syntax &self[begin .. end] or &mut self[begin .. end].

Returns a slice of the given string from the byte range [begin, end).

// byte 2 lies within `ö`:
