Error datatype

Variants

LevelEmpty

When configuring libmcaptcha, 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 libmcaptcha, LevelBuilder. difficulty_factor must be set to greater than zero.

CaptchaDurationZero

captcha cooldown duration must be greater than 0

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

MCaptchaKeyValidationFail

Happens when submitted work is computed over configuration intended for a different mCAptcha sitekey

InvalidPoW

Submitted PoW is invalid

PleaseSetValue(String)

Used in builder structs when a value is not set

RedisError(RedisError)

RedisError

RecvError(RecvError)

Channel receive error

MCaptchaRedisModuleError

Weird behaviour from mcaptcha redis module

MCaptchaRedisModuleIsNotLoaded

When libmcaptcha is ordered to connect to a Redis instance that doesn’t have mCaptcha Redis module loaded

MCaptchaRediSModuleCommandNotFound(String)

MCaptcha redis module is loaded but it doesn’t have the necessary Redis commands. Usually a version mismatch

QueueFull

IP Queue is full

Trait Implementations

impl Debug for CaptchaError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for CaptchaError

fn fmt(&self, _derive_more_display_formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for CaptchaError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl From<MailboxError> for CaptchaError

fn from(_: MailboxError) -> Self

Converts to this type from the input type.

impl From<RecvError> for CaptchaError

fn from(e: RecvError) -> Self

Converts to this type from the input type.

impl From<RedisError> for CaptchaError

fn from(e: RedisError) -> Self

Converts to this type from the input type.

impl PartialEq<CaptchaError> for CaptchaError

fn eq(&self, other: &CaptchaError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
