Enum LoadError 

pub enum LoadError {
    EmptyFilterId,
    FilterIdContainsDelimiter,
    MissingSbom,
    UnverifiedComponentSignature,
    UnverifiedSbomSignature,
    MalformedSbom(Error),
    SbomNotBound,
    UnsupportedContractVersion,
    Instantiate(Error),
    Wasmtime(Error),
}

Why [Host::load] rejected a filter (bp-rust: typed library errors, not ad hoc anyhow::ensure!). Every variant is a fail-closed rejection at the provenance/id gate, before wasmtime ever touches the component bytes — except LoadError::Instantiate / LoadError::Wasmtime, which surface a failure from wasmtime itself (linking / type-checking / the eager trusted-instance build). Host::load’s public signature stays anyhow::Result (unchanged, so plecto-control::ControlError::Load’s existing anyhow::Error passthrough keeps working); callers that want the concrete variant can downcast_ref::<LoadError>().

Variants

EmptyFilterId

FilterIdContainsDelimiter

MissingSbom

UnverifiedComponentSignature

UnverifiedSbomSignature

MalformedSbom(Error)

SbomNotBound

UnsupportedContractVersion

The component’s decoded imports name no recognised plecto:filter@0.N track (absent, or a future version the host does not yet bind). Fail-closed at load — never guess V03.

Instantiate(Error)

The eager trusted-instance build (Host::load’s Isolation::Trusted path) failed — carries the same error RunError::Instantiate would for a later rebuild.

Wasmtime(Error)

Trait Implementations

impl Debug for LoadError

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

Formats the value using the given formatter.

impl Display for LoadError

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

Formats the value using the given formatter.

impl Error for LoadError

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<Error> for LoadError

fn from(source: Error) -> Self

Converts to this type from the input type.
