Struct ConfigError 

pub struct ConfigError {
    pub config: &'static str,
    pub field: &'static str,
    pub kind: ConstraintKind,
}

A single violated configuration invariant.

Names the config type, the offending field, and the specific ConstraintKind. The type is allocation-free — every field is Copy or &'static str — so validation is cheap and ConfigError is PartialEq for straightforward assertions in tests.

use rlevo_core::config::{ConfigError, ConstraintKind};

let err = ConfigError {
    config: "GaConfig",
    field: "pop_size",
    kind: ConstraintKind::Zero,
};
assert!(err.to_string().contains("GaConfig.pop_size"));

Fields

config: &'static str

The config type that failed validation, e.g. "C51TrainingConfig".

field: &'static str

The offending field, e.g. "v_max".

kind: ConstraintKind

The specific invariant that was violated.

Trait Implementations

impl Clone for ConfigError

fn clone(&self) -> ConfigError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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<ConfigError> for EnvironmentError

fn from(source: ConfigError) -> Self

Converts to this type from the input type.

impl PartialEq for ConfigError

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

Equality operator ==.

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

Inequality operator !=.
