std.typecons.Tuple.this
- multiple declarations
Function Tuple.this
Constructor taking one value for each field.
Parameters
Name | Description |
---|---|
values | A list of values that are either the same
types as those given by the Types field
of this Tuple , or can implicitly convert
to those types. They must be in the same
order as they appear in Types . |
Example
alias ISD = Tuple!(int, string, double);
auto tup = ISD(1, "test", 3.2);
writeln(tup .toString()); // `Tuple!(int, string, double)(1, "test", 3.2)`
Function Tuple.this
Constructor taking a compatible array.
this(U, size_t n)
(
U[n] values
)
if (n == Types .length && allSatisfy!(isBuildableFrom!U, Types));
Parameters
Name | Description |
---|---|
values | A compatible static array to build the Tuple from.
Array slices are not supported. |
Example
int[2] ints;
Tuple!(int, int) t = ints;
Function Tuple.this
Constructor taking a compatible Tuple
. Two Tuple
s are compatible
iff they are both of the same length, and, for each type T
on the
left-hand side, the corresponding type U
on the right-hand side can
implicitly convert to T
.
this(U)
(
U another
)
if (areBuildCompatibleTuples!(typeof(this), U));
Parameters
Name | Description |
---|---|
another | A compatible Tuple to build from. Its type must be
compatible with the target Tuple 's type. |
Example
alias IntVec = Tuple!(int, int, int);
alias DubVec = Tuple!(double, double, double);
IntVec iv = tuple(1, 1, 1);
//Ok, int can implicitly convert to double
DubVec dv = iv;
//Error: double cannot implicitly convert to int
//IntVec iv2 = dv;
