Variants

Validation(String)

Module validation error. Might occur only at load time.

Instantiation(String)

Error while instantiating a module. Might occur when provided with incorrect exports (i.e. linkage failure).

Function(String)

Function-level error.

Table(String)

Table-level error.

Memory(String)

Memory-level error.

Global(String)

Global-level error.

Value(String)

Value-level error.

Trap(Trap)

Trap.

Host(Box<dyn HostError>)

Custom embedder error.

Implementations

impl Error

pub fn host<T>(host_error: T) -> Selfwhere T: HostError + Sized,

Creates a new host error.

pub fn as_host_error(&self) -> Option<&dyn HostError>

Returns a reference to a HostError if this Error represents some host error.

I.e. if this error have variant Host or Trap with host error.

pub fn into_host_error(self) -> Option<Box<dyn HostError>>

Returns HostError if this Error represents some host error.

I.e. if this error have variant Host or Trap with host error.

pub fn try_into_host_error(self) -> Result<Box<dyn HostError>, Self>

Returns HostError if this Error represents some host error, otherwise returns the original error.

I.e. if this error have variant Host or Trap with host error.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

The lower-level source of this error, if any.

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

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, demand: &mut Demand<'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 Error

fn from(e: Error) -> Error

Converts to this type from the input type.

impl From<Error> for String

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<Trap> for Error

fn from(e: Trap) -> Error

Converts to this type from the input type.
