Struct ValueValidation 

#[non_exhaustive]
pub struct ValueValidation {
    pub values: Vec<String>,
    /* private fields */
}

Validation based on a list of allowed values.

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.

values: Vec<String>

Required. List of allowed values for the parameter.

Implementations

impl ValueValidation

pub fn new() -> Self

pub fn set_values<T, V>(self, v: T) -> Self

where T: IntoIterator<Item = V>, V: Into<String>,

Sets the value of values.

Example

let x = ValueValidation::new().set_values(["a", "b", "c"]);

Trait Implementations

impl Clone for ValueValidation

fn clone(&self) -> ValueValidation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValueValidation

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

Formats the value using the given formatter.

impl Default for ValueValidation

fn default() -> ValueValidation

Returns the “default value” for a type.

impl Message for ValueValidation

fn typename() -> &'static str

The typename of this message.

impl PartialEq for ValueValidation

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