Enum ComponentDependency 

pub enum ComponentDependency {
    Version(String),
    Package {
        version: String,
        registry: Option<String>,
        package: Option<String>,
        export: Option<String>,
    },
    Local {
        path: PathBuf,
        export: Option<String>,

}

Specifies how to satisfy an import dependency of the component. This may be one of:

• A semantic versioning constraint for the package version to use. Spin fetches the latest matching version of the package whose name matches the dependency name from the default registry.

Example: "my:dep/import" = ">= 0.1.0"

• A package from a registry.

Example: "my:dep/import" = { version = "0.1.0", registry = "registry.io", ...}

• A package from a filesystem path.

Example: "my:dependency" = { path = "path/to/component.wasm", export = "my-export" }

• A component in the application. The referenced component binary is composed: additional configuration such as files, networking, storage, etc. are ignored. This is intended primarily as a convenience for including dependencies in the manifest so that they can be built using spin build.

Example: "my:dependency" = { component = "my-dependency", export = "my-export" }

• A package from an HTTP URL.

Example: "my:import" = { url = "https://example.com/component.wasm", sha256 = "sha256:..." }

Variants

Version(String)

... = ">= 0.1.0"

Package

... = { version = "0.1.0", registry = "registry.io", ...}

Fields

version: String

A semantic versioning constraint for the package version to use. Required. Spin fetches the latest matching version from the specified registry, or from the default registry if no registry is specified.

Example: "my:dep/import" = { version = ">= 0.1.0" }

registry: Option<String>

The registry that hosts the package. If omitted, this defaults to your system default registry.

Example: "my:dep/import" = { registry = "registry.io", version = " 0.1.0" }

package: Option<String>

The name of the package to use. If omitted, this defaults to the package name of the imported interface.

Example: "my:dep/import" = { package = "your:implementation", version = " 0.1.0" }

export: Option<String>

The name of the export in the package. If omitted, this defaults to the name of the import.

Example: "my:dep/import" = { export = "your:impl/export", version = " 0.1.0" }

Local

... = { path = "path/to/component.wasm", export = "my-export" }

Fields

path: PathBuf

The path to the Wasm file that implements the dependency.

Example: "my:dep/import" = { path = "path/to/component.wasm" }

export: Option<String>

The name of the export in the package. If omitted, this defaults to the name of the import.

Example: "my:dep/import" = { export = "your:impl/export", path = "path/to/component.wasm" }

HTTP

... = { url = "https://example.com/component.wasm", sha256 = "..." }

Fields

url: String

The URL to the Wasm component that implements the dependency.

Example: "my:dep/import" = { url = "https://example.com/component.wasm", sha256 = "sha256:..." }

Learn more: https://spinframework.dev/writing-apps#dependencies-from-a-url

digest: String

The SHA256 digest of the Wasm file. This is required for integrity checking. Must begin with sha256:.

Example: "my:dep/import" = { sha256 = "sha256:...", ... }
