Template std.algorithm.searching.all

Checks if all of the elements satisfy pred.

template all(alias pred) ;

Contained Functions

NameDescription
all Returns true if and only if the input range range is empty or all values found in range satisfy the predicate pred. Performs (at most) Ο(range.length) evaluations of pred.

Example

assert( all!"a & 1"([1, 3, 5, 7, 9]));
assert(!all!"a & 1"([1, 2, 3, 5, 7, 9]));

Example

all can also be used without a predicate, if its items can be evaluated to true or false in a conditional statement. This can be a convenient way to quickly evaluate that all of the elements of a range are true.

int[3] vals = [5, 3, 18];
assert( all(vals[]));
