调研方向

Start with the linked CPAL WASM setup wiki page and review the Cargo.toml dependency example described in the issue. Confirm Cargo’s documented restriction on selecting dependencies with debug_assertions, then identify the appropriate feature-based guidance; done when the example no longer uses the unsupported target configuration and explains how to enable the dependency.

描述

dependencies platform - web

I'm following these docs: https://github.com/RustAudio/cpal/wiki/Setting-up-a-new-CPAL-WASM-project

I added this to my Cargo.toml

# The `console_error_panic_hook` crate provides better debugging of panics by
# logging them with `console.error`. This is great for development, but requires
# all the `std::fmt` and `std::panicking` infrastructure, so it's only enabled
# in debug mode.
[target."cfg(debug_assertions)".dependencies]
console_error_panic_hook = "0.1.5"

But it gives this warning:

warning: Found `debug_assertions` in `target.'cfg(...)'.dependencies`. This value is not supported for selecting dependencies and will not work as expected. To learn more visit https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#platform-specific-dependencies

Sadly, that doc says "There is currently no way to add dependencies based on these configuration values."

I think a feature needs to be used instead.
