SetValidator

This class validates input data as a set, ensuring it meets specific length constraints and that each item conforms to a defined sub-validator. It supports both strict and flexible validation modes and can be configured to fail immediately upon the first validation error.

Attributes

Attribute	Type	Description
strict	bool	Determines whether to enforce strict type validation or allow coercion during set membership checks.
item_validator	Arc< CombinedValidator >	The validator instance used to verify and process each individual element within the set.
min_length	Option< usize > = None	The minimum number of unique elements required for the set to be considered valid.
max_length	Option< usize > = None	The maximum number of unique elements allowed in the set before validation fails.
name	String	The identifying label for the validator used in error messages and schema representations.
fail_fast	bool	Indicates whether validation should stop immediately upon encountering the first error within the set items.

Methods

---

validate()

def validate(
    input: Any,
    state: [ValidationState](../validation/state/validationstate.md?sid=validators_validation_state_validationstate)
) - > Set

Validates that the input is a set-like collection and ensures each element conforms to the item validator's constraints.

Parameters

Name	Type	Description
input	Any	The raw input data to be validated as a set collection
state	[ValidationState](../validation/state/validationstate.md?sid=validators_validation_state_validationstate)	The current validation context used for tracking errors and configuration

Returns

Type	Description
Set	A set containing the validated and potentially coerced items from the input collection

---

get_name()

def get_name() - > String

Returns the human-readable name of the validator used for error messages and schema identification.

Returns

Type	Description
String	The name of the validator, typically including the item type (e.g., 'set< int >')
