Struct RunCommand

pub struct RunCommand {
    pub run: RunCommon,
    pub invoke: Option<String>,
    pub preloads: Vec<(String, PathBuf)>,
    pub argv0: Option<String>,
    pub module_and_args: Vec<OsString>,
}

Runs a WebAssembly module

Fields

run: RunCommon

invoke: Option<String>

The name of the function to run

preloads: Vec<(String, PathBuf)>

Load the given WebAssembly module before the main module

argv0: Option<String>

Override the value of argv[0], typically the name of the executable of the application being run.

This can be useful to pass in situations where a CLI tool is being executed that dispatches its functionality on the value of argv[0] without needing to rename the original wasm binary.

module_and_args: Vec<OsString>

The WebAssembly module to run and arguments to pass to it.

Arguments passed to the wasm module will be configured as WASI CLI arguments unless the --invoke CLI argument is passed in which case arguments will be interpreted as arguments to the function specified.

Implementations

impl RunCommand

pub fn execute(self) -> Result<()>

Executes the command.

Trait Implementations

impl Args for RunCommand

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.

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

Append to Command so it can update self.

impl CommandFactory for RunCommand

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 RunCommand

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

Instantiate Self from ArgMatches, parsing the arguments as needed.

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

Instantiate Self from ArgMatches, parsing the arguments as needed.

fn update_from_arg_matches( &mut self, __clap_arg_matches: &ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.

fn update_from_arg_matches_mut( &mut self, __clap_arg_matches: &mut ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.

impl Parser for RunCommand

fn parse() -> Self

Parse from std::env::args_os(), exit on error

fn try_parse() -> Result<Self, Error>

Parse from std::env::args_os(), return Err on error.

fn parse_from<I, T>(itr: I) -> Self

where I: IntoIterator<Item = T>, T: Into<OsString> + Clone,

Parse from iterator, exit on error

fn try_parse_from<I, T>(itr: I) -> Result<Self, Error>

where I: IntoIterator<Item = T>, T: Into<OsString> + Clone,

Parse from iterator, return Err on error.

fn update_from<I, T>(&mut self, itr: I)

where I: IntoIterator<Item = T>, T: Into<OsString> + Clone,

Update from iterator, exit on error

fn try_update_from<I, T>(&mut self, itr: I) -> Result<(), Error>

where I: IntoIterator<Item = T>, T: Into<OsString> + Clone,

Update from iterator, return Err on error.

impl PartialEq for RunCommand

fn eq(&self, other: &RunCommand) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
