CLI args for the wasmer init command

Fields

env: WasmerEnv

lib: bool

Initialize wasmer.toml for a library package

bin: bool

Initialize wasmer.toml for a binary package

empty: bool

Initialize an empty wasmer.toml

overwrite: bool

Force overwriting the wasmer.toml, even if it already exists

quiet: bool

Don’t display debug output

namespace: Option<String>

Namespace to init with, default = current logged in user or _

package_name: Option<String>

Package name to init with, default = Cargo.toml name or current directory name

version: Option<Version>

Version of the initialized package

manifest_path: Option<PathBuf>

If the manifest-path is a Cargo.toml, use that file to initialize the wasmer.toml

template: Option<Template>

Add default dependencies for common packages

include: Vec<String>

Include file paths into the target container filesystem

out: Option<PathBuf>

Directory of the output file name. wasmer init will error if the target dir already contains a wasmer.toml. Also sets the package name.

Implementations

impl Init

fn write_wasmer_toml(path: &PathBuf, toml: &Manifest) -> Result<(), Error>

Writes the metadata to a wasmer.toml file, making sure we include the NOTE so people get a link to the registry docs.

fn target_file(&self) -> Result<(String, PathBuf), Error>

fn get_filesystem_mapping( include: &[String], ) -> impl Iterator<Item = (String, PathBuf)> + '_

fn get_command(modules: &[Module], bin_or_lib: BinOrLib) -> Vec<Command>

fn get_dependencies(template: Option<&Template>) -> IndexMap<String, VersionReq>

Returns the dependencies based on the --template flag

fn get_bin_or_lib(&self) -> Result<BinOrLib, Error>

fn get_bindings( target_file: &Path, bin_or_lib: BinOrLib, ) -> Option<GetBindingsResult>

Get bindings returns the first .wai / .wit file found and optionally takes a warning callback that is triggered when > 1 .wai files are found

Trait Implementations

impl Args for Init

fn group_id() -> Option<Id>

Report the [ArgGroup::id][crate::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]
