Implementations

impl Value

pub fn is_null(&self) -> bool

Returns true when the value is of type Value::Null.

pub fn is_true(&self) -> bool

Returns true when the value is of type Value::Boolean and is equal to true.

pub fn is_number(&self) -> bool

Returns true when the value is of type Value::Number.

pub fn type_of(&self) -> FeelType

Returns the type of this Value.

pub fn coerce(&self, feel_type: &FeelType) -> Value

Applies coercion rules to this value and returns converted value or null.

pub fn try_from_xsd_integer(text: &str) -> Result<Self>

Tries to convert xsd:integer string into valid Value representing a number.

pub fn try_from_xsd_decimal(text: &str) -> Result<Self>

Tries to convert xsd:decimal string into valid Value representing a number.

pub fn try_from_xsd_double(text: &str) -> Result<Self>

Tries to convert xsd:double string into valid Value representing a number.

pub fn try_from_xsd_boolean(text: &str) -> Result<Self>

Tries to convert xsd:boolean string into valid Value representing a boolean.

pub fn try_from_xsd_date(text: &str) -> Result<Self>
