Enum ConfigError 

#[non_exhaustive]
pub enum ConfigError {
    MustBePositive {
        field: &'static str,
    },
    UnsafeSetting {
        field: &'static str,
        because: &'static str,
    },
    Contradiction {
        first: &'static str,
        second: &'static str,
    },
    OutOfRange {
        field: &'static str,
    },
}

A configuration value the library refuses to work with.

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.

MustBePositive

A bound that must allow at least one of something was zero.

Fields

field: &'static str

Dotted path of the field, e.g. execution.max_commands_per_turn.

UnsafeSetting

A safety setting was turned off, and the library has no such mode.

Fields

field: &'static str

Dotted path of the field.

because: &'static str

Why the setting cannot be disabled.

Contradiction

Two settings ask for incompatible things.

Fields

first: &'static str

Dotted path of the first field.

second: &'static str

Dotted path of the second field.

OutOfRange

A ratio expressed in per mille left the 0..=1000 range.

Fields

field: &'static str

Dotted path of the field.

Trait Implementations

impl Clone for ConfigError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ConfigError

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

impl Eq for ConfigError

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<ConfigError> for BuildError

fn from(value: ConfigError) -> Self

Converts to this type from the input type.

impl PartialEq for ConfigError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
