Enum ScanError 

pub enum ScanError {
    Connection(String),
    Backend(String),
    Receive(ReceiveError),
    NotFound(String),
}

Errors from scanning backends.

All backends return this same error type, regardless of data source. Connection and backend errors carry human-readable messages; scanning logic errors wrap ReceiveError transparently.

Variants

Connection(String)

Network connection failure (timeout, DNS, TLS, refused).

Backend(String)

Backend returned invalid or unexpected data.

Receive(ReceiveError)

Scanning logic error (wraps receive crate errors).

NotFound(String)

Block or transaction not found on the backend.

Trait Implementations

impl Debug for ScanError

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

Formats the value using the given formatter.

impl Display for ScanError

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

Formats the value using the given formatter.

impl Error for ScanError

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<ReceiveError> for ScanError

fn from(source: ReceiveError) -> ScanError

Converts to this type from the input type.
