From af323622dbb071a69aa38b60f6d63e0225ff18c8 Mon Sep 17 00:00:00 2001 From: Erich Gubler Date: Thu, 10 Oct 2024 14:28:42 -0400 Subject: [PATCH] refactor: s/once_cell::Lazy/std::sync::LazyLock Weaken our dependence on the `once_cell` crate by using functionality from `std` instead that was upstreamed from `once_cell`, this time with what's available in Rust 1.80+. It's not yet possible to eliminate this dependency entirely, but do what we can for now. --- Cargo.lock | 2 -- benches/Cargo.toml | 1 - benches/benches/computepass.rs | 12 ++++++------ benches/benches/renderpass.rs | 12 ++++++------ benches/benches/resource_creation.rs | 6 +++--- wgpu-hal/Cargo.toml | 1 - wgpu-hal/src/gles/egl.rs | 7 ++++--- wgpu-hal/src/gles/wgl.rs | 7 +++---- 8 files changed, 22 insertions(+), 26 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index 10e5e81d1..95656db1b 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -3605,7 +3605,6 @@ dependencies = [ "criterion", "naga", "nanorand", - "once_cell", "pollster", "profiling", "rayon", @@ -3702,7 +3701,6 @@ dependencies = [ "naga", "ndk-sys", "objc", - "once_cell", "parking_lot", "profiling", "range-alloc", diff --git a/benches/Cargo.toml b/benches/Cargo.toml index ba47bc1b6..d3e496650 100644 --- a/benches/Cargo.toml +++ b/benches/Cargo.toml @@ -43,7 +43,6 @@ naga = { workspace = true, features = [ "wgsl-out", ] } nanorand.workspace = true -once_cell.workspace = true pollster.workspace = true profiling.workspace = true rayon.workspace = true diff --git a/benches/benches/computepass.rs b/benches/benches/computepass.rs index 2a5a9d3a0..d6cd10713 100644 --- a/benches/benches/computepass.rs +++ b/benches/benches/computepass.rs @@ -5,8 +5,8 @@ use std::{ use criterion::{criterion_group, Criterion, Throughput};
