Variants

Bool(bool)

Boolean value.

Int64

Float64

64-bit IEEE 754 float (NaN not allowed) with optional unit.

Fields

value: f64

unit: Option<Id>

Implementations

impl Value<'_>

pub fn data_type(&self) -> DataType

Returns the data type of this value.

pub fn validate(&self) -> Option<&'static str>

Validates this value according to spec rules.

Returns an error description if invalid, None if valid.

Trait Implementations

impl<'a> Clone for Value<'a>

fn clone(&self) -> Value<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Value<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for Value<'a>

fn eq(&self, other: &Value<'a>) -> 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.
