Static WASM_C_ABI

pub static WASM_C_ABI: &'static Lint

The wasm_c_abi lint detects crate dependencies that are incompatible with future versions of Rust that will emit spec-compliant C ABI.

Example

#![deny(wasm_c_abi)]

This will produce:

error: the following packages contain code that will be rejected by a future version of Rust: wasm-bindgen v0.2.87

  |         ^^^^^^^^^^

Explanation

Rust has historically emitted non-spec-compliant C ABI. This has caused incompatibilities between other compilers and Wasm targets. In a future version of Rust this will be fixed and therefore dependencies relying on the non-spec-compliant C ABI will stop functioning.
