Struct wasmcloud_host::NativeCapability

pub struct NativeCapability { /* fields omitted */ }

Represents a native capability provider compiled as a shared object library. These plugins are OS- and architecture-specific, so they will be .so files on Linux, .dylib files on macOS, etc.

Implementations

impl NativeCapability

pub fn from_archive(
    archive: &ProviderArchive,
    link_target_name: Option<String>
) -> Result<Self>

Reads a capability provider from an archive file. The right architecture/OS plugin library will be chosen from the file, or an error will result if it isn’t found.

pub fn from_instance(
    instance: impl CapabilityProvider + 'static,
    link_target_name: Option<String>,
    claims: Claims<CapabilityProvider>
) -> Result<Self>

This function is to be used for capability embedding. If you are building a custom wasmcloud host and have a fixed set of capabilities that you want to always be available to actors, then you can declare a dependency on the capability provider, enable the static_plugin feature, and provide an instance of that provider. Be sure to check that the provider supports capability embedding. You must also provide a set of valid claims that can be generated from a signed JWT

pub fn id(&self) -> String

Returns the unique ID (public key/subject) of the capability provider

pub fn cache_path(&self) -> PathBuf

Trait Implementations

impl Clone for NativeCapability

fn clone(&self) -> NativeCapability

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
