|
|
Due to instability in the Rust WASM ecosystem, the trunk build
|
|
tool enforces that the Cargo-dependency version of `wasm-bindgen`
|
|
MUST match the version of the CLI supplied in the environment.
|
|
|
|
This can get out of sync when nixpkgs is updated. To resolve it,
|
|
wasm-bindgen must be bumped in the Cargo.toml file and cargo needs
|
|
to be run to resolve the dependencies.
|
|
|
|
Versions of `wasm-bindgen` in Cargo.toml:

Expected: '= ${pkgs.wasm-bindgen-cli.version}'
