Module error 

Structs

Error

An engine error. JavaScript exceptions will eventually carry a heap value; this type is also usable before a context exists (lexer and decoder errors).

NativeErrorMessage

Raw bytes produced by QuickJS’s stack-local char buf[256] native-error formatter. The payload silently stops at 255 bytes; JavaScript String construction observes only the prefix before the first formatted NUL.
