Struct CountBound 

pub struct CountBound {
    pub gte: Option<usize>,
    pub lte: Option<usize>,
    pub eq: Option<usize>,
}

Count bound specification supporting gte/lte/eq constraints

Fields

gte: Option<usize>

Greater than or equal to (minimum count)

lte: Option<usize>

Less than or equal to (maximum count)

eq: Option<usize>

Exactly equal to (exact count)

Implementations

impl CountBound

pub fn gte(value: usize) -> Self

Create a new CountBound with only gte constraint

pub fn lte(value: usize) -> Self

Create a new CountBound with only lte constraint

pub fn eq(value: usize) -> Self

Create a new CountBound with only eq constraint

pub fn range(min: usize, max: usize) -> Result<Self>

Create a new CountBound with range (gte and lte)

pub fn validate(&self, actual: usize, context: &str) -> Result<()>

Validate that a count satisfies this bound

Trait Implementations

impl Clone for CountBound

fn clone(&self) -> CountBound

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CountBound

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CountBound

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CountBound

fn eq(&self, other: &CountBound) -> 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 CountBound

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
