Hi,
I'd like to use a binary heap from @safe code. I thought @safe is
transitive but the following example does not compile:
import std.container.binaryheap;
@safe // This makes things fail.
unittest
{
// Test range interface.
import std.algorithm.comparison : equal;
int

It tries too but "heapify" uses the struct "BinaryHeap" that is
not safe at all.
(either not annotated or @safe not applicable because of what

I have a static array of `ubyte`s of arbitrary size:
```d
ubyte[4] x = [ // in reality, ubyte[64]
0b1000,
0b0001,
0b00010101,
0b0010,
];
```
Now I want to bit-rotate the array as if it is one big integer.
So:
```d
ubyte[n] rotateRight(size_t n)(ref const ubyte[n] a

You may find `std.bitmanip.BitArray` useful for this:

cast as uint and shift. cast the result as ubyte[4].
obiously, that works for n=4 with uint and n=8 for ulong
Hi,
I'm trying to compile a simple app with D code to Android and
trying to use the d_android library for this. While trying to
compile a basic sample, I found a README [0] that mentions an
"android-dub-build.d" script, which should be a wrapper around
`dub build`, but I cannot find this file

Ah, I forgot to update that file. There is no android-dub-bu
So the correct steps now:
1) get ldc 1.19 specifically and the android NDK
2) do `android-setup /path/to/your/android/ndk`
3) do normal `dub build`
Sorry, I must have misread this. My LDC version was 1.20.1, not
1.19.
Thanks

did that fix the linker error?
The runtimes it downloads are specifically built against 1.19.
But lib

do
ldc2 -v
and it will tell you where the config file is.
open that up and see if it

Hello,
I'm trying to upgrade and improve an Android project I was
working on a while ago. For this reason, I decided to upgrade my
compiler to the newest LDC (v1.23.0).
I am using the arsd.jni library for the JNI headers and for
initializing the runtime. However, I am getting linker errors,

Perhaps you happen to use some stale artifacts? These magic
