Enum Length

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

The length of a value 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 HasLength property trait.

Variants

Max(usize)

The length of the value must be less than or equal to the specified maximum

Min(usize)

The length of the value must be greater than or equal to the specified minimum

MinMax(usize, usize)

The length of the value must be between the specified minimum and maximum (inclusive)

Exact(usize)

The value must be of an exact length

Trait Implementations

impl Clone for Length

fn clone(&self) -> Length

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Length

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

Formats the value using the given formatter.

impl PartialEq for Length

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

impl<T> Validate<Length, FieldName> for T

where T: HasLength,

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

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

impl Copy for Length

impl Eq for Length

impl StructuralPartialEq for Length
