Enum McError 

pub enum McError {
    Network(NetworkError),
    Protocol(ProtocolError),
    Io(Error),
    Config(ConfigError),
}

Top-level error type returned by all fallible operations in this library.

See the module documentation for matching examples and retry guidance.

Variants

Network(NetworkError)

A network-layer failure: DNS lookup, TCP/UDP connect, or timeout.

See NetworkError for specific variants.

Protocol(ProtocolError)

A protocol-level failure: the server sent a response that could not be parsed.

See ProtocolError for specific variants.

Io(Error)

An OS-level I/O error, e.g. a file could not be written when saving a favicon.

Config(ConfigError)

An invalid configuration value was provided by the caller.

See ConfigError for specific variants.

Trait Implementations

impl Debug for McError

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

Formats the value using the given formatter.

impl Display for McError

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

Formats the value using the given formatter.

impl Error for McError

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.
