Implementations

impl VariantTypeId

pub fn is_numeric(&self) -> bool

Tests and returns true if the variant holds a numeric type

pub fn precedence(&self) -> u8

Returns a data precedence rank for scalar types, OPC UA part 4 table 119. This is used when operators are comparing values of differing types. The type with the highest precedence dictates how values are converted in order to be compared.

Trait Implementations

impl Clone for VariantTypeId

fn clone(&self) -> VariantTypeId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VariantTypeId

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

Formats the value using the given formatter.

impl PartialEq<VariantTypeId> for VariantTypeId

fn eq(&self, other: &VariantTypeId) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl TryFrom<&'_ NodeId> for VariantTypeId

type Error = ()

The type returned in the event of a conversion error.

fn try_from(value: &NodeId) -> Result<Self, Self::Error>

Performs the conversion.
