Enum WasmError 

#[non_exhaustive]
pub enum WasmError {
    InvalidWasm(String),
    Instantiate(String),
    Invoke(String),
    Ipc(IpcError),
    ResourceLimit(String),

}

Errors specific to the WASM loader.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidWasm(String)

The supplied WASM bytes failed to parse or validate.

Instantiate(String)

Component instantiation failed.

Invoke(String)

A plugin export call trapped or returned a fn-error.

Ipc(IpcError)

Arrow IPC marshalling across the linear-memory boundary failed.

ResourceLimit(String)

Wall-clock or fuel deadline exceeded.

Internal(String)

Internal / unexpected error.

AbiUnsupported

The plugin’s declared ABI range does not intersect any host-supported major (per the multi-version Linker cache in crate::multi_version).

Fields

requested: String

The plugin’s manifest abi range string.

supported: Vec<u64>

Host-supported major versions.

Trait Implementations

impl Debug for WasmError

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

Formats the value using the given formatter.

impl Display for WasmError

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

Formats the value using the given formatter.

impl Error for WasmError

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<IpcError> for WasmError

fn from(source: IpcError) -> Self

Converts to this type from the input type.

impl PoolResourceLimit for WasmError

fn resource_limit(msg: String) -> Self

Construct a “resource limit exceeded” instance from a diagnostic message. Called when the pool’s max_instances is reached.
