Struct WasmConfig

pub struct WasmConfig {
    pub created: DateTime<Utc>,
    pub author: Option<String>,
    pub architecture: String,
    pub os: String,
    pub layer_digests: Vec<String>,
    pub component: Option<Component>,
}

The config type struct for application/wasm

Fields

created: DateTime<Utc>

The time when the config was created.

author: Option<String>

The optional name of the author of the config.

architecture: String

The architecture of the artifact. This is always wasm.

os: String

The OS name of the artifact. Possible options: wasip1, wasip2. For plain wasm, this should be wasip1 as this must match a GOOS value and it doesn’t have one for plain Wasm

Eventually this will go away when we hit a 1.0 but we need it for now

layer_digests: Vec<String>

This field contains a list of digests of each of the layers from the manifest in the same order as they are listed in the manfiest. This exists because we need to have a unique list here so that the hash of the config (used as the ID) is unique every time (https://github.com/opencontainers/image-spec/pull/1173)

component: Option<Component>

Information about the component in the manifest. This is required when the os field is wasip2

Implementations

impl WasmConfig

pub async fn from_component( path: impl AsRef<Path>, author: Option<String>, ) -> Result<(Self, ImageLayer)>

A helper for loading a component from a file and returning the proper config and ImageLayer. The returned config will have the created time set to now and all other fields set for a component.

pub fn from_raw_component( raw: Vec<u8>, author: Option<String>, ) -> Result<(Self, ImageLayer)>

Same as WasmConfig::from_component but for raw component bytes

pub async fn from_module( path: impl AsRef<Path>, author: Option<String>, ) -> Result<(Self, ImageLayer)>

A helper for loading a plain wasm module and returning the proper config and ImageLayer. The returned config will have the created time set to now and all other fields set for a plain wasm module.

pub fn from_raw_module( raw: Vec<u8>, author: Option<String>, ) -> Result<(Self, ImageLayer)>

Same as WasmConfig::from_module but for raw module bytes

pub fn with_annotations( &self, annotations: BTreeMap<String, String>, ) -> AnnotatedWasmConfig<'_>

Adds annotations to this WasmConfig.
