Struct std.array.RefAppender
A version of Appender
that can update an array in-place.
It forwards all calls to an underlying appender implementation.
Any calls made to the appender also update the pointer to the
original array passed in.
struct RefAppender(A)
if (isDynamicArray!A);
Constructors
Name | Description |
---|---|
this
(arr)
|
Constructs a RefAppender with a given array reference. This does not copy the
data. If the array has a larger capacity as determined by arr , it
will be used by the appender.
|
Properties
Name | Type | Description |
---|---|---|
capacity [get]
|
size_t | Returns the capacity of the array (the maximum number of elements the
managed array can accommodate before triggering a reallocation). If any
appending will reallocate, capacity returns 0 .
|
opSlice [get]
|
inout(ElementEncodingType!A)[] |
Methods
Name | Description |
---|---|
opDispatch
(args)
|
Wraps remaining Appender methods such as put .
|
opOpAssign
(rhs)
|
Appends rhs to the managed array.
|
Tip
Use the arrayPtr
overload of appender
for construction with type-inference.
Parameters
Name | Description |
---|---|
A | The array type to simulate |
Example
int[] a = [1, 2];
auto app2 = appender(&a);
writeln(app2[]); // [1, 2]
writeln(a); // [1, 2]
app2 ~= 3;
app2 ~= [4, 5, 6];
writeln(app2[]); // [1, 2, 3, 4, 5, 6]
writeln(a); // [1, 2, 3, 4, 5, 6]
app2 .reserve(5);
assert(app2 .capacity >= 5);
