Expand description

Errors that can occur when processing CORS guarded requests.

## 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.

### `WildcardOrigin`

Allowed origin argument must not be wildcard (`*`).

### `MissingOrigin`

Request header `Origin` is required but was not provided.

### `MissingRequestMethod`

Request header `Access-Control-Request-Method` is required but is missing.

### `BadRequestMethod`

Request header `Access-Control-Request-Method` has an invalid value.

### `BadRequestHeaders`

Request header `Access-Control-Request-Headers` has an invalid value.

### `OriginNotAllowed`

Origin is not allowed to make this request.

### `MethodNotAllowed`

Request method is not allowed.

### `HeadersNotAllowed`

One or more request headers are not allowed.
