Struct RequiredIfAbsentValidator 

pub struct RequiredIfAbsentValidator;

Validates conditional requirement based on absence: if one field is missing, others must be provided.

Example

use fraiseql_core::validation::mutual_exclusivity::RequiredIfAbsentValidator;
use serde_json::json;
// If addressId is not provided, then street, city, zip must all be provided
let input = json!({ "addressId": null, "street": "123 Main St", "city": "Springfield", "zip": "12345" });
assert!(
    RequiredIfAbsentValidator::validate(&input, "addressId", &["street".to_string(), "city".to_string(), "zip".to_string()], None).is_ok(),
    "required-if-absent constraint satisfied when absent field is null and all required fields present"
);

Implementations

impl RequiredIfAbsentValidator

pub fn validate( input: &Value, absent_field: &str, then_required: &[String], context_path: Option<&str>, ) -> Result<()>

Validate that if absent_field is absent/null, all then_required fields must be provided.

Errors

Returns FraiseQLError::Validation if the condition field is absent and any required field is also missing.
