Enum Error 

#[non_exhaustive]
pub enum Error {
    Io(Error),
    Env {
        name: String,
        source: VarError,
    },
    AddrParse(AddrParseError),
    PortParse(ParseIntError),
    LocalIp(Error),
    Nacos(Error),
    InvalidConfig(String),
}

Errors produced during service-discovery operations.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Io(Error)

I/O error, typically from the underlying network or runtime setup.

Env

Failed to read an environment variable.

Fields

name: String

Name of the environment variable.

source: VarError

Underlying cause.

AddrParse(AddrParseError)

Failed to parse a socket address.

PortParse(ParseIntError)

Failed to parse a port number.

LocalIp(Error)

Failed to detect the local IP address.

Nacos(Error)

Error raised by the Nacos client during build or registration.

InvalidConfig(String)

Invalid configuration (missing required fields, malformed address, etc.).

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
