Error datatype

Variants

LevelEmpty

When configuring m_captcha, DefenseBuilder must be passed atleast one LevelConfig if not this error will arise

DifficultyFactorZero

Visitor count must be a whole number(zero and above). When configuring m_captcha, LevelBuilder. difficulty_factor must be set to greater than zero.

SetDifficultyFactor

Difficulty factor must be set

SetVisitorThreshold

Visitor threshold must be set

DuplicateVisitorCount

Visitor count must be Unique

DecreaseingDifficultyFactor

Difficulty factor should increase with level

MailboxError

Difficulty factor should increase with level

InsuffiencientDifficulty

Happens when submitted work doesn't satisfy the required difficulty factor

StringNotFound

Happens when submitted work is computed over string that isn't in cache
