Enum RewardError 

pub enum RewardError {
    ContentNotRegistered(String),
    InvalidProof,
    DatabaseError(String),
    CalculationFailed(String),
    InsufficientBalance,
    CreatorNotFound(String),

Reward calculation errors.

Examples

use chie_shared::RewardError;

// Content registration check
fn calculate_reward(content_cid: &str, registered: bool) -> Result<u64, RewardError> {
    if !registered {
        return Err(RewardError::ContentNotRegistered(content_cid.to_string()));
    }
    Ok(100) // 100 points
}

// Balance check
fn withdraw_points(amount: u64, balance: u64) -> Result<u64, RewardError> {
    if amount > balance {
        Err(RewardError::InsufficientBalance)
    } else {
        Ok(balance - amount)
    }
}

// Reward amount validation
fn validate_reward(amount: u64) -> Result<u64, RewardError> {
    if amount > 1_000_000 {
        Err(RewardError::InvalidRewardAmount(amount))
    } else {
        Ok(amount)
    }
}

assert_eq!(calculate_reward("QmTest", true).unwrap(), 100);
assert!(calculate_reward("QmTest", false).is_err());
assert_eq!(withdraw_points(50, 100).unwrap(), 50);
assert!(withdraw_points(150, 100).is_err());
assert!(validate_reward(500).is_ok());
assert!(validate_reward(2_000_000).is_err());

Trait Implementations

impl Debug for RewardError

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

Formats the value using the given formatter.

impl Display for RewardError

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

Formats the value using the given formatter.

impl Error for RewardError

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

Returns 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.
