Are collections supported?
Is this the correct way to use them, it seems to work:
struct MyStruct {
a: usize,
b: usize,
}
let bvec: &mut Vec<MyStruct> = gr.bumpalo_herd.get().alloc(vec![]);
bvec.push(MyStruct {
a: 12,
b: 53,
});
for x in bvec {
println!("{}/{}", x.a, x.b);
}
cargo miri test
changed to be more compatible with cargo test
, but this means we had to find a different way to pass flags to the interpreter, so there now is a MIRIFLAGS
environment variable for that. The old way still works for now, but is deprecated.
This affects the following line:
Line 20 in 3590e4e
cargo miri test miri
(running the same tests as cargo test miri
).First of all I'd like to say that it is a great crate and it is very relevant to my work.
While working with it I came a cross of several ideas, not sure if @vorner would find them adequate:
get_by_id()
method which would allow to get a Bump attached to some kind of resource - a thread for example. Members acquired in such a way would not be shared between different resources - only within one resource designated by some kind of user-provided ID (thread ID, worker ID, coroutine ID, whatever).reset_unsafe()
method so that if user could reset an individual member if he really knows what he's doing. That is supposed to play together with the above method.In latest Rust nightly we can allocate with custom allocator (for example https://doc.rust-lang.org/nightly/alloc/vec/struct.Vec.html#method.new_in).
It will be great for bumpalo-herd to provide the ability to use this. To achieve this, we need to implement std::alloc::AllocRef
.
