Struct wasmer_config::package::Manifest

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

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

Fields (Non-exhaustive)§

This struct is marked as 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: Option<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.

Implementations§

source§

impl Manifest

source

pub fn builder(package: Package) -> ManifestBuilder

Create a ManifestBuilder populated with all mandatory fields.

source

pub fn parse(s: &str) -> Result<Self, Error>

Parse a Manifest from its TOML representation.

source

pub fn find_in_directory<T: AsRef<Path>>(path: T) -> Result<Self, ManifestError>

Construct a manifest by searching in the specified directory for a manifest file.

source

pub fn validate(&self) -> Result<(), ValidationError>

Validate this Manifest to check for common semantic errors.

Some common error cases are:

  • Having multiple modules with the same name
  • Having multiple commands with the same name
  • A Command that references a non-existent Module in the current package
  • A Package::entrypoint which points to a non-existent Command
source

pub fn add_dependency( &mut self, dependency_name: String, dependency_version: VersionReq )

add a dependency

source

pub fn remove_dependency(&mut self, dependency_name: &str) -> Option<VersionReq>

remove dependency by package name

source

pub fn to_string(&self) -> Result<String>

Convert a Manifest to its TOML representation.

source

pub fn save(&self, path: impl AsRef<Path>) -> Result<()>

Write the manifest to permanent storage
