Enum LoadError 

#[non_exhaustive]
pub enum LoadError {
    Io {
        path: PathBuf,
        message: String,
    },
    UnknownKind {
        path: PathBuf,
    },
    Unsupported {
        path: PathBuf,
        feature: &'static str,
    },
    NotAPlugin {
        path: PathBuf,
        message: String,
    },
    Abi {
        path: PathBuf,
        error: AbiError,
    },
    Limit {
        path: PathBuf,
        message: String,
    },
}

Why a runtime plugin could not be loaded. Every variant names the path.

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.

Io

The file could not be read or opened.

Fields

path: PathBuf

message: String

UnknownKind

Not a .wasm, .so, .dylib or .dll file.

Fields

path: PathBuf

Unsupported

This build cannot load that kind: it needs feature.

Fields

path: PathBuf

feature: &'static str

NotAPlugin

The file is not a plugin: an export or symbol is missing or wrong.

Fields

path: PathBuf

message: String

Abi

The plugin’s description was refused (ABI version, names, kinds).

Fields

path: PathBuf

error: AbiError

Limit

The plugin exceeded a limit (fuel, memory, size) while loading.

Fields

path: PathBuf

message: String

Implementations

impl LoadError

pub fn path(&self) -> &Path

The path that failed.

Trait Implementations

impl Clone for LoadError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for LoadError

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 PartialEq for LoadError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
