// Nonce validation

        Ok(())
    }
}

// Latency check
fn validate_latency(latency_ms: u32) -> Result<(), VerificationError> {
    if latency_ms > 5000 {
        Err(VerificationError::InvalidLatency(latency_ms))
    } else {
        Ok(())

Trait Implementations

impl Debug for VerificationError

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

Formats the value using the given formatter.

impl Display for VerificationError

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

Formats the value using the given formatter.

impl Error for VerificationError

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.

impl From<ValidationError> for VerificationError

fn from(err: ValidationError) -> Self

Converts to this type from the input type.
