Enum Dialect 

pub enum Dialect {
    Xsd,
    Xpath,
    Xpath20,
}

Source-level dialect. XSD §F.1 forbids ^ and $ (patterns are implicitly whole-input anchored); XPath 2.0 §7.6 keeps the XSD grammar but adds them back as explicit anchors usable anywhere in the pattern.

Variants

Xsd

XSD Part 2 §F — what xs:pattern facets compile under.

Xpath

XPath 2.0 §7.6 — what fn:matches, fn:replace, fn:tokenize, and xsl:analyze-string compile under in XSLT 3.0+ hosts. Adds explicit anchors ^ / $ and non-capturing (?:...) groups on top of the XSD grammar.

Xpath20

XPath 2.0 §7.6 strict — same as Dialect::Xpath but without the XPath 3.0 extensions ((?:…) / inline flags). Used by XSLT 2.0 hosts where the W3C conformance suite expects FORX0002 on the 3.0 extensions.

Trait Implementations

impl Clone for Dialect

fn clone(&self) -> Dialect

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Dialect

impl Debug for Dialect

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

Formats the value using the given formatter.

impl Eq for Dialect

impl Hash for Dialect

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Dialect

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
