    pub rule_violated: String,
    pub location: Vec<String>,
}

Error type for pattern validation failures.

Provides detailed information about what rule was violated and where in the pattern structure the violation occurred.

Examples

use pattern_core::ValidationError;

let error = ValidationError {
    message: "Pattern depth exceeds maximum".to_string(),
    rule_violated: "max_depth".to_string(),
    location: vec!["elements".to_string(), "0".to_string()],
};

Fields

message: String

Human-readable error message

rule_violated: String

Name of violated rule (e.g., “max_depth”, “max_elements”)

location: Vec<String>

Path to violating node in pattern structure

Trait Implementations

impl Clone for ValidationError

fn clone(&self) -> ValidationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidationError

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

Formats the value using the given formatter.

impl PartialEq for ValidationError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
