Protocol-level errors.

Examples

use chie_shared::ProtocolError;

// Network error example
fn connect_to_peer(peer_id: &str) -> Result<(), ProtocolError> {
    if peer_id.is_empty() {
        return Err(ProtocolError::PeerNotFound("empty peer ID".to_string()));
    }
    Ok(())
}

// Content lookup error
fn get_content(cid: &str) -> Result<Vec<u8>, ProtocolError> {
    if cid.starts_with("Qm") {
        Ok(vec![1, 2, 3])
    } else {
        Err(ProtocolError::ContentNotFound(cid.to_string()))
    }
}

// Rate limiting
fn check_rate_limit(request_count: u32) -> Result<(), ProtocolError> {
    if request_count > 100 {
        Err(ProtocolError::RateLimitExceeded)
    } else {
        Ok(())
    }
}

assert!(connect_to_peer("12D3Koo").is_ok());
assert!(get_content("QmTest").is_ok());
assert!(check_rate_limit(50).is_ok());
assert!(check_rate_limit(150).is_err());

Trait Implementations

impl Debug for ProtocolError

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

Formats the value using the given formatter.

impl Display for ProtocolError

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

Formats the value using the given formatter.

impl Error for ProtocolError

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 ProtocolError

fn from(err: ValidationError) -> Self

Converts to this type from the input type.
