Struct ValidationRules 

pub struct ValidationRules {
    pub max_depth: Option<usize>,
    pub max_elements: Option<usize>,
    pub required_fields: Vec<String>,
}

Configurable validation rules for pattern structure.

Rules can specify limits on nesting depth, element counts, or other structural properties. Rules are optional (None means no limit).

Examples

use pattern_core::ValidationRules;

// No constraints (all patterns valid)
let rules = ValidationRules::default();

// Maximum depth constraint
let rules = ValidationRules {
    max_depth: Some(10),
    ..Default::default()
};

Fields

max_depth: Option<usize>

Maximum nesting depth allowed (None = no limit)

max_elements: Option<usize>

Maximum element count allowed (None = no limit)

required_fields: Vec<String>

Required fields (reserved for future value-specific validation)

Trait Implementations

impl Clone for ValidationRules

fn clone(&self) -> ValidationRules

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidationRules

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

Formats the value using the given formatter.

impl Default for ValidationRules

fn default() -> ValidationRules

Returns the “default value” for a type.
