Function rt.lifetime._d_arraycatnTX

Concatenate multiple arrays at once

extern(C) void[] _d_arraycatnTX (
  const(TypeInfo) ti,
  scope byte[][] arrs
);

This is more efficient than repeatedly concatenating pairs of arrays because the total size is known in advance.

` void main() { int[] a, b, c; int[] res = a ~ b ~ c; // d_arraycatnTX(typeid(int[]), // [(cast(byte*)a.ptr)[0..a.length], (cast(byte*)b.ptr)[0..b.length], (cast(byte*)c.ptr)[0..c.length]]); } `

Parameters

NameDescription
ti type of arrays to concatenate and resulting array
arrs array of arrays to concatenate, cast to byte[] while keeping .length the same

Returns

newly created concatenated array, .length equal to the total element length despite void type
