Description

Span [constructor]

Constructors

at

Returns a reference to the `i`th element, with bounds checking.

back

Returns a reference to the last element; the span must not be empty.

begin

Returns an iterator to the first element.

cbegin

Returns a const iterator to the first element.

cend

Returns a const iterator just past the last element.

crbegin

Returns a const reverse iterator to the last element.

crend

Returns a const reverse iterator just before the first element.

data

Returns a pointer to the span's underlying array of data.

empty

Reports whether this span is empty.

end

Returns an iterator just past the last element.

first

Returns a span containing the first len elements.

front

Returns a reference to the first element; the span must not be empty.

last

Returns a span containing the last len elements.

length

Returns the length (size) of this span.

operator[]

Returns a reference to the `i`th element of this span.

rbegin

Returns a reverse iterator to the last element.

remove_prefix

Removes the first n elements from the span.

remove_suffix

Removes the last n elements from the span.

rend

Returns a reverse iterator just before the first element.

size

Returns the number of elements in this span.

subspan

Returns a subspan starting at pos and spanning len elements.

Name

Description

npos

Sentinel size value meaning "until the end of the span".
