Struct ValidationEnum 

#[non_exhaustive]
pub struct ValidationEnum {
    pub strict: bool,
    pub values: Option<Vec<String>>,
}

Defines enumeration validation for attribute values. Allows specifying a list of permitted values and whether custom values beyond the enumerated list are allowed.

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.

strict: bool

Boolean that defaults to false. When true, only values specified in the enum list are allowed. When false, custom values beyond the enumerated list are permitted.

values: Option<Vec<String>>

A list of predefined values that are allowed for this attribute. These values are always permitted regardless of the Strict setting.

Implementations

impl ValidationEnum

pub fn strict(&self) -> bool

Boolean that defaults to false. When true, only values specified in the enum list are allowed. When false, custom values beyond the enumerated list are permitted.

pub fn values(&self) -> &[String]

A list of predefined values that are allowed for this attribute. These values are always permitted regardless of the Strict setting.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .values.is_none().

impl ValidationEnum

pub fn builder() -> ValidationEnumBuilder

Creates a new builder-style object to manufacture ValidationEnum.

Trait Implementations

impl Clone for ValidationEnum

fn clone(&self) -> ValidationEnum

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidationEnum

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

Formats the value using the given formatter.

impl PartialEq for ValidationEnum

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