Struct DeclarePattern 

pub struct DeclarePattern {
    pub xpath: String,
    pub pattern_type: DeclarePatternType,
    pub base_text: Option<String>,
    pub sub_text: Option<String>,
    pub accent_name: Option<String>,
    pub has_wildcard: bool,
    pub wildcard_paths: Option<Vec<Vec<usize>>>,
    pub font_class: Option<&'static str>,
}

Metadata for a compiled \lxDeclare pattern. Contains the XPath, pattern type for Rust-side filtering, and wildcard info.

Fields

xpath: String

pattern_type: DeclarePatternType

base_text: Option<String>

Base token text for subscript/prime/accent base matching (e.g. “x”)

sub_text: Option<String>

For literal subscripts: the subscript content text (e.g. “1”)

accent_name: Option<String>

For accent patterns: the accent name (e.g. “hat”)

has_wildcard: bool

wildcard_paths: Option<Vec<Vec<usize>>>

font_class: Option<&'static str>

Font CLASS the matched base must carry (e.g. “caligraphic”), checked Rust-side — never baked into the XPath (see base_text_predicate).

Implementations

impl DeclarePattern

pub fn select_count(&self) -> Option<usize>

Number of sibling nodes the match spans — Perl’s $nnodes from domToXPath (Rewrite.pm). Subscript/prime patterns match the base XMTok plus its POSTSUBSCRIPT/POSTSUPERSCRIPT sibling; accents match the single XMApp; function applications span base + ( + n args + (n-1) commas + ).

Trait Implementations

impl Clone for DeclarePattern

fn clone(&self) -> DeclarePattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeclarePattern

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

Formats the value using the given formatter.
