Struct RunWasm

pub struct RunWasm { /* private fields */ }

Low level control over run-wasm for integration within your own custom xtask

When run() is called it will:

1. Compile the rust project to wasm
2. Run wasm-bindgen
3. Generate an index.html that runs the wasm
4. Launch a tiny webserver to serve index.html + your wasm

It will block forever to keep the webserver running until killed with ctrl-c or similar

Implementations

impl RunWasm

pub fn new() -> Self

pub fn with_css(self, css: &str) -> Self

css to include on the served webpage. By default no css is included, which results in the default webpage styling which includes margins around the body. It is common to want a fullscreen wasm gui with no webpage margins which can be achieved via:

RunWasm::new()
    .with_css("body { margin: 0px; }")
    .run();

pub fn with_package(self, package: Option<String>) -> Self

Package with the target to run

pub fn with_example(self, example: Option<String>) -> Self

Name of the example target to run

pub fn with_bin(self, bin: Option<String>) -> Self

Name of the bin target to run

pub fn with_profile(self, profile: Option<String>) -> Self

Build artifacts with the specified profile

pub fn with_cargo_build_args(self, cargo_build_args: Vec<String>) -> Self

pub fn with_build_only(self, build_only: bool) -> Self

Only build the WASM artifacts, do not run the dev server

pub fn with_host(self, host: Option<String>) -> Self

Makes the dev server listen on host (default ‘localhost’)

pub fn with_port(self, port: Option<String>) -> Self

Makes the dev server listen on port (default ‘8000’)

pub fn run(self) -> Result<(), String>

Launch run-wasm
