Struct Value 

pub struct Value {
    pub value: ValueData,
    pub output: OutputSpec,
}

A concrete type that implements atomic values. These are the 19 predefined types in XSD Schema Part 2, plus five additional types. Also included is a hint for serialisation for if the value should be escaped.

Fields

value: ValueData

output: OutputSpec

Implementations

impl Value

pub fn value_ref(&self) -> &ValueData

pub fn output_ref(&self) -> &OutputSpec

impl Value

pub fn new_time(t: DateTime<Local>) -> Self

Create a Time, ignoring the date part

pub fn new_date(d: NaiveDate) -> Self

pub fn to_bool(&self) -> bool

Give the effective boolean value.

pub fn to_int(&self) -> Result<i64, Error>
