Function std.algorithm.comparison.equal.equal
Compares two ranges for equality. The ranges may have
different element types, as long as pred(r1
evaluates to bool
.
Performs Ο(min(r1
) evaluations of pred
.
bool equal(Range1, Range2)
(
Range1 r1,
Range2 r2
)
if (isInputRange!Range1 && isInputRange!Range2 && !(isInfinite!Range1 && isInfinite!Range2) && is(typeof(binaryFun!pred(r1 .front, r2 .front))));
At least one of the ranges must be finite. If one range involved is infinite, the result is
(statically known to be) false
.
If the two ranges are different kinds of UTF code unit (char
, wchar
, or
dchar
), then the arrays are compared using UTF decoding to avoid
accidentally integer-promoting units.
Parameters
Name | Description |
---|---|
r1 | The first range to be compared. |
r2 | The second range to be compared. |
Returns
true
if and only if the two ranges compare equal element
for element, according to binary predicate pred
.
