Enum passwordmaker_rs::SettingsError

pub enum SettingsError {
    InsufficientCharset,
}

Error returned if creation of a PasswordMaker object failed due to invalid settings.

Description

InsufficientCharset means that the output character set does not contain at least two grapheme clusters. Since the output string is computed by doing a base system conversion from binary to number-of-grapheme-clusters, any number of grapheme clusters lower than 2 forms a nonsensical input. There simply is no base-1 or base-0 number system.

Variants

InsufficientCharset

Password generation failed, because the character set supplied by the user did not contain at least 2 grapheme clusters.
