Struct sgx_tstd::ops::Range 1.0.0[−][src]
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 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 = ['a', 'b', 'c', 'd']; assert_eq!(arr[ .. ], ['a', 'b', 'c', 'd']); assert_eq!(arr[ ..3], ['a', 'b', 'c', ]); assert_eq!(arr[1.. ], [ 'b', 'c', 'd']); assert_eq!(arr[1..3], [ 'b', 'c' ]); // Range
Fields
start: Idx
The lower bound of the range (inclusive).
end: Idx
The upper bound of the range (exclusive).

🔬 This is a nightly-only experimental API. (range_contains
)
recently added as per RFC
Returns true
if item
is contained in the range.
Examples
#![feature(range_contains)] use std::f32; assert!(!(3..5).contains(&2)); assert!( (3..5).contains(&3)); assert!( (3..5).contains(&4)); assert!(!(3..5).contains(&5)); assert!(!(3..3).contains(&3)); assert!(!(3..2).contains(&3)); assert!( (0.0..1.0).contains(&0.5)); assert!(!(0.0..1.0).contains(&f32::NAN)); assert!(!(0.0..f32::NAN).contains(&0.5)); assert!(!(f32::NAN..1.0).contains(&0.5));
pub fn is_empty(&self) -> bool
[src]
pub fn is_empty(&self) -> bool
🔬 This is a nightly-only experimental API. (range_is_empty
)
recently added
Returns true
if the range contains no items.
Examples
#![feature(range_is_empty)] assert!(!(3..5).is_empty()); assert!( (3..3).is_empty()); assert!( (3..2).is_empty());
The range is empty if either side is incomparable:
#![feature(range_is_empty)] use std::f32::NAN; assert!(!(3.0..5.0).is_empty()); assert!( (3.0..NAN).is_empty()); assert!( (NAN..5.0).is_empty());

impl Index<Range<usize>> for str
[src]
impl Index<Range<usize>> for str
Implements substring slicing with syntax &self[begin .. end]
.
Returns a slice of the given string from the byte range
[begin
..end
).
This operation is O(1)
.
Panics
Panics if begin
or end
does not point to the starting
byte offset of a character (as defined by is_char_boundary
).
Requires that begin <= end
and end <= len
where len
is the
length of the string.
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];
type Output = str
The returned type after indexing.
