The command-line interface for Perseus, a super-fast WebAssembly frontend development framework!

Fields

subcmd: Subcommand

cargo_engine_path: String

The path to cargo when used for engine builds

cargo_browser_path: String

The path to cargo when used for browser builds

wasm_bindgen_path: Option<String>

A path to wasm-bindgen, if you want to use a local installation (note that the CLI will install it locally for you by default)

wasm_opt_path: Option<String>

A path to wasm-opt, if you want to use a local installation (note that the CLI will install it locally for you by default)

rustup_path: String

The path to rustup

wasm_release_rustflags: String

The value of RUSTFLAGS when building for Wasm in release mode (this will not impact internal target-gating)

cargo_engine_args: String

Any arguments to cargo when building for the engine-side

cargo_browser_args: String

Any arguments to cargo when building for the browser-side

wasm_bindgen_args: String

Any arguments to wasm-bindgen

wasm_opt_args: String

Any arguments to wasm-opt (only run in release builds)

git_path: String

The path to git (for downloading custom templates for perseus new)

reload_server_host: String

The host for the reload server (you should almost never change this)

reload_server_port: u16

The port for the reload server (you should almost never change this)

sequential: bool

If this is set, commands will be run sequentially rather than in parallel (slows down operations, but reduces memory usage)

no_browser_reload: bool

Disable automatic browser reloading

wasm_bindgen_version: Option<String>

A custom version of wasm-bindgen to use (defaults to the latest installed version, and after that the latest available from GitHub; update to latest can be forced with latest)

wasm_opt_version: Option<String>

A custom version of wasm-opt to use (defaults to the latest installed version, and after that the latest available from GitHub; update to latest can be forced with latest)

no_system_tools_cache: bool

Disables the system-wide tools cache in ~/.cargo/perseus_tools/ (you should set this for CI)

verbose: bool

Shows the logs from building and serving your app no matter what (the default is to only show them on a compilation/build failure); this is intended mainly for end-to-end debugging, although the snoop commands are more useful for targeted debugging

Trait Implementations

impl Args for Opts

fn group_id() -> Option<Id>

Report the ArgGroup::id for this set of arguments

fn augment_args<'b>(__clap_app: Command) -> Command

Append to Command so it can instantiate Self via FromArgMatches::from_arg_matches_mut

fn augment_args_for_update<'b>(__clap_app: Command) -> Command

Append to Command so it can instantiate self via FromArgMatches::update_from_arg_matches_mut

impl Clone for Opts

fn clone(&self) -> Opts

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl CommandFactory for Opts

fn command<'b>() -> Command

Build a Command that can instantiate Self.

fn command_for_update<'b>() -> Command

Build a Command that can update self.

impl FromArgMatches for Opts

fn from_arg_matches(__clap_arg_matches: &ArgMatches) -> Result<Self, Error>
