Struct cargo_wasmer::Pack

#[non_exhaustive]
pub struct Pack {
    pub manifest: Manifest,
    pub workspace: Workspace,
    pub features: Features,
    pub debug: bool,
    pub out_dir: Option<PathBuf>,
}

Compile a Rust crate to a WAPM package.

Examples

use clap::Parser;
use cargo_wasmer::Pack;

let pack = Pack::parse();
let meta = pack.metadata()?;

for pkg in pack.resolve_packages(&meta) {
    let dest = pack.generate_wapm_package(pkg, meta.target_directory.as_ref())?;
    println!("Wrote the WAPM package for {} to {}", pkg.name, dest.display());
}

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

manifest: Manifest

workspace: Workspace

features: Features

debug: bool

Compile in debug mode.

out_dir: Option<PathBuf>

Where to save the compiled WAPM package(s)

Implementations

impl Pack

pub fn metadata(&self) -> Result<Metadata, Error>

Use the cargo metadata subcommand to learn about the workspace.

pub fn resolve_packages<'meta>( &self, metadata: &'meta Metadata ) -> Vec<&'meta Package>

Figure out which packages the user wants to pack.

pub fn generate_wasmer_package( &self, pkg: &Package, target_dir: &Path ) -> Result<PathBuf, Error>

Compile a crate to a Wasmer package and save it on disk.

Trait Implementations

impl Args for Pack

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 Pack

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 Debug for Pack

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Pack

fn default() -> Pack

Returns the “default value” for a type.

impl FromArgMatches for Pack

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 Pack

fn parse() -> Self

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

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

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

fn parse_from<I, T>(itr: I) -> Selfwhere 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<RichFormatter>>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<RichFormatter>>where I: IntoIterator<Item = T>, T: Into<OsString> + Clone,
