Configuration error type

Defines all possible error scenarios in the configuration system.

Examples

use qubit_config::{Config, ConfigError, ConfigResult};
fn get_port(config: &Config) -> ConfigResult<i32> { unimplemented!() }

Trait Implementations

impl Debug for ConfigError

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

Formats the value using the given formatter.

impl Display for ConfigError

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

Formats the value using the given formatter.

impl Error for ConfigError

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<Error> for ConfigError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<ValueError> for ConfigError

fn from(err: ValueError) -> Self

Converts to this type from the input type.
