Enum PluginLoaderError 

pub enum PluginLoaderError {
    Manifest(ManifestError),
    Host(PluginHostError),
    NotWired(&'static str),
    NothingLoaded,
    Discovery(String),
    NotLoaded(String),
    NotReloadable(String),
}

Why a plugin failed to load. Every variant is graceful-degradation input for the caller (discovery logs + skips; the editor never aborts boot on one bad plugin) — the load path returns a value, never panics.

Variants

Manifest(ManifestError)

The manifest was malformed or declared an unrecognised capability/seam.

Host(PluginHostError)

The component failed to compile, instantiate, activate, or spawn a seam — a wasm trap, fuel/epoch exhaustion, or a capability failure.

NotWired(&'static str)

A seam was declared but the loader was constructed without the editor environment needed to drive it (the minimal test constructor). Never happens on the real boot path.

NothingLoaded

The plugin declared no seam the loader can drain yet, so nothing loaded.

Discovery(String)

:plugin-load <path> pointed at a directory that is not a plugin (no plugin.toml, bad TOML, or missing/ambiguous component).

NotLoaded(String)

:plugin-unload / :plugin-reload <target> named no currently-loaded plugin (by manifest id or numeric plugin id).

NotReloadable(String)

:plugin-reload on a plugin the loader can’t re-read from disk (loaded from bytes in a test, or its source dir is gone).

Trait Implementations

impl Debug for PluginLoaderError

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

Formats the value using the given formatter.

impl Display for PluginLoaderError

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

Formats the value using the given formatter.

impl Error for PluginLoaderError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<ManifestError> for PluginLoaderError

fn from(source: ManifestError) -> Self

Converts to this type from the input type.

impl From<PluginHostError> for PluginLoaderError

fn from(source: PluginHostError) -> Self

Converts to this type from the input type.
