Enum hentai::HentaiError

pub enum HentaiError {
    IoError(Error),
    BaseError(&'static str),
    HttpError(Error),
    UriError(InvalidUri),
    SerdeError(Error),
    ToStrError(ToStrError),
    ConversionError(ParseIntError),
}

Global error type for Hentai that catches all other types of errors that may occur. This still provides the original error message when printed.

The first type (IOError) can only occur when using the Hentai::from_json() constructor. Typically, the cause of this is an invalid file path being provided.

BaseError is a standard error used to indicate that an Option<> failed to be converted into a Result<>. This occurs in the Hentai::random() constructor after the request is sent but the redirect header cannot be converted into a string.

HttpError and UriError only occur when using Hentai::new(). HttpErrors occur when hyper is unable to complete the request. UriErrors are usually caused by an invalid code being provided, thus resulting in an invalid URI.

SerdeError means that the JSON was invalid and it could not be deserialized.

ToStrError happens when using Hentai::random() and the redirect header cannot be converted into a random doujin URL.

ConversionError happens when the response from nhentai’s /random endpoint returns a URL from which the six-digit code could not be converted into an integer. The cause of this is currently unknown, but please crate an issue on GitHub if you know how to fix this.
