Implementations

impl VariantTypeId

pub fn encoding_mask(&self) -> u8

pub fn from_encoding_mask(
encoding_mask: u8
) -> Result<VariantTypeId, StatusCode>

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.
