Variants (Non-exhaustive)
This enum is marked as 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.
Global(GlobalError)
A global variable error.
Memory(MemoryError)
A linear memory error.
Table(TableError)
A table error.
Linker(LinkerError)
A linker error.
Instantiation(InstantiationError)
A module instantiation error.
Module(ModuleError)
A module compilation, validation and translation error.
Func(FuncError)
A function error.
Trap(Trap)
A trap as defined by the WebAssembly specification.
