Struct rocket::mtls::oid::asn1_rs::nom::lib::std::ops::RangeFrom

1.0.0 · source ·
pub struct RangeFrom<Idx> {
    pub start: Idx,
}
Available on crate feature mtls only.
Expand description

A range only bounded inclusively below (start..).

The RangeFrom start.. contains all values with x >= start.

Note: Overflow in the Iterator implementation (when the contained data type reaches its numerical limit) is allowed to panic, wrap, or saturate. This behavior is defined by the implementation of the Step trait. For primitive integers, this follows the normal rules, and respects the overflow checks profile (panic in debug, wrap in release). Note also that overflow happens earlier than you might assume: the overflow happens in the call to next that yields the maximum value, as the range must be set to a state to yield the next value.

§Examples

The start.. syntax is a RangeFrom:

assert_eq!((2..), std::ops::RangeFrom { start: 2 });
assert_eq!(2 + 3 + 4, (2..).take(3).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]); // This is a `RangeFrom`
assert_eq!(arr[1.. 3], [   1, 2      ]);
assert_eq!(arr[1..=3], [   1, 2, 3   ]);

Fields§

§start: Idx

The lower bound of the range (inclusive).

fn index_mut(self, slice: &mut [T]) -> &mut [T]

Returns a mutable reference to the output at this location, panicking if out of bounds.
1.20.0 (const: unstable) · source§

impl SliceIndex<str> for RangeFrom<usize>

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

Returns a slice of the given string from the byte range [begin, len). Equivalent to &self[begin .. len] or &mut self[begin .. len].

This operation is O(1).

Prior to 1.20.0, these indexing operations were still supported by direct implementation of Index and IndexMut.

§Panics

Panics if begin does not point to the starting byte offset of a character (as defined by is_char_boundary), or if begin > len.
