Enum valid::constraint::CharCount

pub enum CharCount {
    Max(usize),
    Min(usize),
    MinMax(usize, usize),
    Exact(usize),
}

The number of characters must be within some bounds.

The validation function can be applied in the FieldName context. It is implemented for all types T that implement the HasCharCount property trait.

Variants

Max(usize)

The number of characters must be less than or equal to the specified maximum

Min(usize)

The number of characters must be greater than or equal to the specified minimum

MinMax(usize, usize)

The number of characters must be between the specified minimum and maximum (inclusive)

Exact(usize)

The number of characters must be equal to the specified amount

Trait Implementations

impl Clone for CharCount

fn clone(&self) -> CharCount

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for CharCount

impl Eq for CharCount

impl PartialEq<CharCount> for CharCount

fn eq(&self, other: &CharCount) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &CharCount) -> bool

This method tests for !=.

impl StructuralEq for CharCount

impl StructuralPartialEq for CharCount

impl<T> Validate<CharCount, FieldName> for T where
    T: HasCharCount, 

fn validate(
    self,
    name: impl Into<FieldName>,
    constraint: &CharCount
) -> Validation<CharCount, Self>

Validates this value for being compliant to the specified constraint C in the given context S.
