Enum LengthAssertion 

pub enum LengthAssertion {
    Min(usize),
    Max(usize),
    Between(usize, usize),
    Exactly(usize),
    NotEmpty,
}

Types of length assertions that can be made.

Variants

Min(usize)

String must be at least this length

Max(usize)

String must be at most this length

Between(usize, usize)

String length must be between min and max (inclusive)

Exactly(usize)

String must be exactly this length

NotEmpty

String must not be empty (convenience for Min(1))

Trait Implementations

impl Clone for LengthAssertion

fn clone(&self) -> LengthAssertion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LengthAssertion

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LengthAssertion

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for LengthAssertion

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

Formats the value using the given formatter.

impl PartialEq for LengthAssertion

fn eq(&self, other: &LengthAssertion) -> 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 Serialize for LengthAssertion

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
