Variants

ToJsConversionError

A Rust value could not be converted to a JavaScript value.

Fields of ToJsConversionError

from: &'static str

Name of the Rust type that could not be converted.

to: &'static str

Name of the JavaScript type that could not be created.

FromJsConversionError

A JavaScript value could not be converted to the expected Rust type.

Fields of FromJsConversionError

from: &'static str

Name of the JavaScript type that could not be converted.

to: &'static str

Name of the Rust type that could not be created.

RuntimeError

An error that occurred within the scripting environment.

Fields of RuntimeError

code: RuntimeErrorCode

A code representing what type of error occurred.

name: String

A string representation of the type of error.

RecursiveMutCallback

A mutable callback has triggered JavaScript code that has called the same mutable callback again.

This is an error because a mutable callback can only be borrowed mutably once.

ExternalError(Box<dyn RuntimeError + 'static>)

A custom error that occurs during runtime.

This can be used for returning user-defined errors from callbacks.

NotAFunction

An error specifying the variable that was called as a function was not a function.
