Source
#[non_exhaustive]
pub enum JsNativeErrorKind {    Aggregate(Vec<JsError>),    Error,    Eval,    Range,    Reference,    Syntax,    Type,    Uri,    NoInstructionsRemain,    RuntimeLimit,}
Expand description

The list of possible error types aJsNativeError can be.

More information:

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.
§

Aggregate(Vec<JsError>)

A collection of errors wrapped in a single error.

More information:

§

Error

A generic error. Commonly used as the base for custom exceptions.

More information:

§

Eval

An error related to the global functioneval().

More information:

§

Range

An error thrown when a value is outside its valid range.

More information:

§

Reference

An error representing an invalid de-reference of a variable.

More information:

§

Syntax

An error representing an invalid syntax in the Javascript language.

More information:

§

Type

An error thrown when a variable or argument is not of a valid type.

More information:

§

Uri

An error thrown when theencodeURI() anddecodeURI() functions receiveinvalid parameters.

More information:

§

NoInstructionsRemain

Error thrown when no instructions remain. Only used in a fuzzing context; not a valid JSerror variant.

§

RuntimeLimit

Error thrown when a runtime limit is exceeded. It’s not a valid JS error variant.
