Implementations§

Source§

impl TypeConverter

Source

pub fn new() -> Self

Create a new type converter

Source

pub fn with_validators(validators: ValidatorRegistry) -> Self

Create with a custom validator registry

Source

pub fn cast( &self, value: &XmlValue, target: XmlTypeCode, ) -> ConversionResult<XmlValue>

Cast a value to the target type

This is the strict casting operation used by cast as.

Source

pub fn to_string(&self, value: &XmlValue) -> String

Convert value to string

Source

pub fn to_boolean(&self, value: &XmlValue) -> ConversionResult<bool>

Convert value to boolean (effective boolean value)

Source

pub fn to_double(&self, value: &XmlValue) -> ConversionResult<f64>

Convert value to double (numeric promotion)

Source

pub fn to_decimal(&self, value: &XmlValue) -> ConversionResult<Decimal>

Convert value to decimal

Source

pub fn to_integer(&self, value: &XmlValue) -> ConversionResult<BigInt>

Convert value to integer

Source

pub fn matches(&self, value: &XmlValue, seq_type: &SequenceType) -> bool

Check if value matches the given sequence type

Source

pub fn promote_numeric( &self, left: XmlTypeCode, right: XmlTypeCode, ) -> Option<XmlTypeCode>

Apply type promotion for numeric operations

Returns the promoted type for two operands in an arithmetic operation.

Source

pub fn promote_to( &self, value: &XmlValue, target: XmlTypeCode, ) -> ConversionResult<XmlValue>

Promote a value to the target numeric type
