Internal interpreter error.

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

Creates a new host error.

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.

Returns HostError if this Error represents some host error.

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

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.
