Struct PatternFacet 

pub struct PatternFacet {
    pub value: String,
    pub source: Option<SourceRef>,
    /* private fields */
}

Pattern facet (regex constraint)

Fields

value: String

The pattern string (XSD regex syntax)

source: Option<SourceRef>

Implementations

impl PatternFacet

pub fn new( value: String, source: Option<SourceRef>, xsd_version: XsdVersion, regex_compat: RegexCompat, ) -> FacetResult<Self>

Create a new pattern facet from an XSD pattern string.

The pattern is validated and compiled using the appropriate backend (XSD 1.0: regex via convert_xml_pattern; XSD 1.1: regexml after a \p{X} rewrite if xsd_version == V1_0). Returns an error if the pattern is invalid.

xsd_version controls the \p{X} category escape semantics: under V1_0 recognized general-category names are expanded to Unicode 3.0 ranges; V1_1 passes them through to the backend unchanged.

regex_compat controls grammar leniency: Strict enforces XSD Part 2 §F/§G; LenientMs first applies lenient_ms_preprocess to drop start/end anchors and (?#…) comments common in .NET-authored schemas.

pub fn new_unchecked(value: String, source: Option<SourceRef>) -> Self

Create a pattern facet without compiling (for deferred compilation)

pub fn compile( &mut self, xsd_version: XsdVersion, regex_compat: RegexCompat, ) -> FacetResult<()>

Compile the pattern if not already compiled

pub fn matches(&self, value: &str) -> bool

Test if a value matches this pattern
