Function validate_id 

pub fn validate_id(id: &str, policy: IDPolicy) -> Result<(), IDValidationError>

Validate an ID string against the configured ID policy

Arguments

• id - The ID value to validate
• policy - The ID policy to enforce

Returns

Ok(()) if the ID is valid for the policy, Err(IDValidationError) otherwise

Errors

Returns IDValidationError if the ID does not conform to the specified policy. For IDPolicy::UUID, the ID must be a valid UUID. For IDPolicy::OPAQUE, any string is valid.

Examples

use fraiseql_core::validation::{IDPolicy, validate_id};

// UUID policy enforces UUID format
assert!(
    validate_id("550e8400-e29b-41d4-a716-446655440000", IDPolicy::UUID).is_ok(),
    "valid UUID should pass UUID policy"
);
assert!(
    validate_id("not-uuid", IDPolicy::UUID).is_err(),
    "non-UUID string should fail UUID policy"
);

// OPAQUE policy accepts any string
assert!(
    validate_id("anything", IDPolicy::OPAQUE).is_ok(),
    "OPAQUE policy should accept any string"
);
assert!(
    validate_id("", IDPolicy::OPAQUE).is_ok(),
    "OPAQUE policy should accept empty string"
);

Errors

Returns IDValidationError if id does not conform to policy (e.g., not a valid UUID when IDPolicy::UUID is used).
