Function std.range.primitives.front
Implements the range interface primitive front
for built-in
arrays. Due to the fact that nonmember functions can be called with
the first argument using the dot notation, array
is
equivalent to front(array)
. For narrow strings, front
automatically returns the first code point as a dchar
.
ref inout(T) front(T)
(
scope return inout(T)[] a
) pure nothrow @nogc @property @safe
if (!(autodecodeStrings && isNarrowString!(T[])) && !is(T[] == void[]));
dchar front(T)
(
scope const(T)[] a
) pure @property @safe
if (autodecodeStrings && isNarrowString!(T[]));
Example
int[] a = [ 1, 2, 3 ];
writeln(a .front); // 1
