⚠️ NOTICE for `metal` users on `gpu-allocator 0.26` ⚠️

[MarijnS95]

gpu-allocator 0.26 was just published with metal support! Unfortunately the metal-rs crate that is used is heavily unmaintained, and some functions used by gpu-allocator are not yet available in the upstream metal-rs release. Attempts to contribute have thus far gone unnoticed.

This was worked around by a patch in Cargo.toml which does not translate to the crates.io release, so anyone turning on the not-default metal feature will get a compilation failure in gpu-allocator.

The workaround is to adopt the same [patch.crates-io] into your workspace root, while we work to resolve this issue upstream:

gpu-allocator/Cargo.toml

Lines 100 to 101 in cbf5299

	[patch.crates-io]
	metal = { git = "https://github.com/Traverse-Research/metal-rs", rev = "a354c33" }

A planned upgrade to objc2 and objc2-metal is happening in #225 🎉

[MarijnS95]

This was fixed by using stable metal 0.29 complete will all necessary changes in the published gpu-allocator 0.27 release.
