| |
| Diagnostics WASM is a set of build rules and libraries to build |
| rustc\_library targets as .wasm libraries, with generated bindings. |
| |
| WARNING: These build templates are for use only under |
| //src/diagnostics. All other uses are unsupported and may break without |
| warning. |
| |
| ## Building |
| |
| This project can be added to builds by including `--with //src/diagnostics/wasm` to the `fx |
| set` invocation. |
| |
| ## Using |
| |
| Diagnostics WASM can be used by using the following import in BUILD.gn: |
| |
| ``` |
| import("//src/diagnostics/wasm/rustc_wasm.gni") |
| ``` |
| |
| For an example, see [//src/diagnostics/wasm/example](example). |
| |
| Diagnostics WASM is not available in the SDK. |
| |
| ## Source layout |
| |
| The main .gni and helpers for the build rule exist in this top-level directory. |
| |
| Our in-tree implementation of the wasm-bindgen CLI is under "bindgen." |
| |
| The example library exists under "example." |
