Implementations

source

impl Value

source

pub fn is_null(&self) -> bool

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

source

pub fn is_true(&self) -> bool

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

source

pub fn is_number(&self) -> bool

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

source

pub fn type_of(&self) -> FeelType

Returns the type of this Value.

source

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

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

source

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

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

source

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

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

source

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

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

source

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

Tries to convert xsd:date string into valid Value representing a date. FEEL date format is fully conformant with xsd:date.

source

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

Tries to convert xsd:time string into valid Value representing a time. FEEL time format is fully conformant with xsd:time.

source

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

Tries to convert xsd:dateTime string into valid Value representing a date and time. FEEL date and time format is fully conformant with xsd:dateTime.

source

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

Tries to convert xsd:duration string into valid Value representing a date and time. FEEL durations are conformant with xsd:duration but spit into two ranges.
