Struct LoadedPlugin 

pub struct LoadedPlugin {
    pub manifest: PluginManifest,
    pub source: Option<PathBuf>,
    /* private fields */
}

Fields

manifest: PluginManifest

source: Option<PathBuf>

Path the plugin was loaded from. None if loaded from embedded bytes (include_bytes!).

Implementations

impl LoadedPlugin

pub fn from_file(path: PathBuf, max_instances: usize) -> Result<Self>

Build a plugin from an on-disk .wasm file. The Extism manifest disables WASI filesystem access entirely (host-mediated reads only).

Two-phase load: instantiate with no allowed hosts, read the plugin’s PluginManifest, then rebuild the pool with the allowlist the plugin declared. The throwaway pool is dropped before the real one is built.

pub fn from_bytes(bytes: &'static [u8], max_instances: usize) -> Result<Self>

Build a plugin from embedded bytes (used for in-tree builtins).

Two-phase load: see LoadedPlugin::from_file.

pub async fn call_capability<I, O>(&self, export: &str, input: &I) -> Result<O>

where I: Serialize + Sync, O: DeserializeOwned,

Call a capability export. Acquires a pool slot for the duration of the call, then returns it. Generic over the input/output types.

The Send + Sync bound on I is required so the returned future is Send — chain tasks await this future across a tokio::spawn boundary.

Trait Implementations

impl Debug for LoadedPlugin

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
