drain_filter not found error in connect.rs

[ccleavinger]

I was following Phaestus Fox's bevy 2d platformer tutorial and git cloned his repo when I tried to run it I got this error:

error[E0599]: no method named drain_filter found for struct std::collections::HashMap in the current scope --> C:\Users\caleb.cargo\git\checkouts\belly-6f46a1ea7d2f8371\2157ac7\crates\belly_core\src\relations\connect.rs:314:33 | 314 | connections.sources.drainfilter(|entity, | { | --------------------^^^^^^^^^^^^ method not found in HashMap<Option<Entity>, Vec<(Option<Entity>, Handler<Q, E>)>>

I've seen people mention that this is a nightly feature and I've built with my rust-toolchain.toml set to nightly and stable, both times I've gotten this exact same error.

Looks like the belly version should be specified. The platformer repo uses own belly fork: https://github.com/PhaestusFox/bevy_platformer/blob/be3859de4a6c12fd712dfd13fb7946333b251c03/Cargo.toml#L22C1-L22C57

It probably will compile if you use original repo and specify exact revesion, something like:

belly = {git="https://github.com/jkb0o/belly.git" rev="ddd29fc" }

Ok thanks! Sorry for the issue, still new to rust.
