Struct lunatic::LunaticError

pub struct LunaticError { /* fields omitted */ }

An opaque error returned from host calls.

Host calls can have a big number of failure reasons and it’s impossible to enumerate all of them. This is especially true for calls that involve compiling raw binary data to WebAssembly modules. Because of this an opaque error ID is returned from host that can be transformed to a string.
