Struct Validation 

#[non_exhaustive]
pub struct Validation {
    pub min_length: i32,
    pub max_length: i32,
    pub min_values: i32,
    pub max_values: i32,
    pub ignore_case: bool,
    pub minimum: f64,
    pub maximum: f64,
    pub exclusive_minimum: f64,
    pub exclusive_maximum: f64,
    pub multiple_of: f64,
    pub enum: Option<ValidationEnum>,
}

Defines validation rules for data table attribute values. Based on JSON Schema Draft 2020-12 with additional Connect-specific validations. Validation rules ensure data integrity and consistency across the data table.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

min_length: i32

The minimum number of characters a text value can contain. Applies to TEXT value type and values within a TEXT_LIST. Must be less than or equal to MaxLength.

max_length: i32

The maximum number of characters a text value can contain. Applies to TEXT value type and values within a TEXT_LIST. Must be greater than or equal to MinLength.

min_values: i32

The minimum number of values in a list. Must be an integer greater than or equal to 0 and less than or equal to MaxValues. Applies to all list types.

max_values: i32

The maximum number of values in a list. Must be an integer greater than or equal to 0 and greater than or equal to MinValues. Applies to all list types.

ignore_case: bool

Boolean that defaults to false. Applies to text lists and text primary attributes. When true, enforces case-insensitive uniqueness for primary attributes and allows case-insensitive lookups.

minimum: f64

The smallest inclusive numeric value for NUMBER value type. Cannot be provided when ExclusiveMinimum is also provided. Must be less than or equal to Maximum and less than ExclusiveMaximum. Applies to NUMBER and values within NUMBER_LIST.

maximum: f64

The largest inclusive numeric value for NUMBER value type. Can be provided alongside ExclusiveMaximum where both operate independently. Must be greater than or equal to Minimum and greater than ExclusiveMinimum. Applies to NUMBER and values within NUMBER_LIST.

exclusive_minimum: f64

The smallest exclusive numeric value for NUMBER value type. Can be provided alongside Minimum where both operate independently. Must be less than ExclusiveMaximum and Maximum. Applies to NUMBER and values within NUMBER_LIST.

exclusive_maximum: f64

The largest exclusive numeric value for NUMBER value type. Can be provided alongside Maximum where both operate independently. Must be greater than ExclusiveMinimum and Minimum. Applies to NUMBER and values within NUMBER_LIST.

multiple_of: f64

Specifies that numeric values must be multiples of this number. Must be greater than 0. The result of dividing a value by this multiple must result in an integer. Applies to NUMBER and values within NUMBER_LIST.

enum: Option<ValidationEnum>

Defines enumeration constraints for attribute values. Can specify a list of allowed values and whether custom values are permitted beyond the enumerated list.

Implementations

impl Validation

pub fn min_length(&self) -> i32

The minimum number of characters a text value can contain. Applies to TEXT value type and values within a TEXT_LIST. Must be less than or equal to MaxLength.

pub fn max_length(&self) -> i32

The maximum number of characters a text value can contain. Applies to TEXT value type and values within a TEXT_LIST. Must be greater than or equal to MinLength.

pub fn min_values(&self) -> i32

The minimum number of values in a list. Must be an integer greater than or equal to 0 and less than or equal to MaxValues. Applies to all list types.

pub fn max_values(&self) -> i32

The maximum number of values in a list. Must be an integer greater than or equal to 0 and greater than or equal to MinValues. Applies to all list types.

pub fn ignore_case(&self) -> bool

Boolean that defaults to false. Applies to text lists and text primary attributes. When true, enforces case-insensitive uniqueness for primary attributes and allows case-insensitive lookups.

pub fn minimum(&self) -> f64

The smallest inclusive numeric value for NUMBER value type. Cannot be provided when ExclusiveMinimum is also provided. Must be less than or equal to Maximum and less than ExclusiveMaximum. Applies to NUMBER and values within NUMBER_LIST.

pub fn maximum(&self) -> f64

The largest inclusive numeric value for NUMBER value type. Can be provided alongside ExclusiveMaximum where both operate independently. Must be greater than or equal to Minimum and greater than ExclusiveMinimum. Applies to NUMBER and values within NUMBER_LIST.

pub fn exclusive_minimum(&self) -> f64

The smallest exclusive numeric value for NUMBER value type. Can be provided alongside Minimum where both operate independently. Must be less than ExclusiveMaximum and Maximum. Applies to NUMBER and values within NUMBER_LIST.

pub fn exclusive_maximum(&self) -> f64

The largest exclusive numeric value for NUMBER value type. Can be provided alongside Maximum where both operate independently. Must be greater than ExclusiveMinimum and Minimum. Applies to NUMBER and values within NUMBER_LIST.

pub fn multiple_of(&self) -> f64

Specifies that numeric values must be multiples of this number. Must be greater than 0. The result of dividing a value by this multiple must result in an integer. Applies to NUMBER and values within NUMBER_LIST.

pub fn enum(&self) -> Option<&ValidationEnum>

Defines enumeration constraints for attribute values. Can specify a list of allowed values and whether custom values are permitted beyond the enumerated list.

impl Validation

pub fn builder() -> ValidationBuilder

Creates a new builder-style object to manufacture Validation.

Trait Implementations

impl Clone for Validation

fn clone(&self) -> Validation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Validation

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

Formats the value using the given formatter.

impl PartialEq for Validation

fn eq(&self, other: &Validation) -> 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.
