Struct wasmer_toml::Manifest

#[non_exhaustive]
pub struct Manifest {
    pub package: Package,
    pub dependencies: HashMap<String, VersionReq>,
    pub fs: IndexMap<String, PathBuf>,
    pub modules: Vec<Module>,
    pub commands: Vec<Command>,
}

The manifest represents the file used to describe a Wasm package.

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.

package: Package

Metadata about the package itself.

dependencies: HashMap<String, VersionReq>

The package’s dependencies.

fs: IndexMap<String, PathBuf>

The mappings used when making bundled assets available to WebAssembly instances, in the form guest -> host.

modules: Vec<Module>

WebAssembly modules to be published.

commands: Vec<Command>

Commands the package makes available to users.
