Struct PackageGet 

pub struct PackageGet {
    pub env: WasmerEnv,
    pub package: String,
}

Show basic metadata of a package without unpacking or downloading it.

The package can be a directory containing a wasmer.toml file, a .webc file, or a package name from the registry. If no argument is given, the current directory is used.

Fields

env: WasmerEnv

package: String

The package to show.

This can be a path to a package directory or a .webc file, or the name of a package in the registry (e.g. wasmer/hello@=0.1.0).

Implementations

impl PackageGet

async fn load_manifest(&self) -> Result<(Manifest, Option<String>)>

Resolve the package argument into a Manifest, whether it points to a local package or a package in the registry.

The second tuple element is a link to the package’s page on the registry web frontend, present only when the package was resolved from a named registry lookup (local files and hashes have no such page).

Trait Implementations

impl Args for PackageGet

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]
