Struct ockam_core::lib::Range

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

A (half-open) range bounded inclusively below and exclusively above (start..end).

The range start..end contains all values with start <= x < end. It is empty if start >= end.

Examples

The start..end syntax is a Range:

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      ]); // This is a `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].

Examples

let s = "Löwe 老虎 Léopard";
assert_eq!(&s[0 .. 1], "L");

assert_eq!(&s[1 .. 9], "öwe 老");

// these will panic:
// byte 2 lies within `ö`:
// &s[2 ..3];

// byte 8 lies within `老`
// &s[1 .. 8];

// byte 100 is outside the string
// &s[3 .. 100];
