Trait Implementations

impl Debug for ConfigError

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

Formats the value using the given formatter.

impl Display for ConfigError

Formats high-level config errors by delegating to their underlying causes.

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

Formats one high-level config error for display.

Arguments

• self: Error value to format.
• f: Formatter receiving the rendered message.

Returns

Returns the formatter result.

Examples

let _ = ();

impl Error for ConfigError

Exposes the wrapped source error for high-level config failures.

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the wrapped high-level source error.

Arguments

• self: Error value whose source should be exposed.

Returns

Returns the wrapped source error for this variant.

Examples

let _ = ();

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.
