Struct ProcessingMode 

pub struct ProcessingMode {
    pub rules: HashMap<String, Vec<ConstructionRule>>,
    pub default_rule: Option<Value>,
}

Processing mode containing construction rules

Corresponds to OpenJade’s ProcessingMode class. Stores all element construction rules defined in the template.

Fields

rules: HashMap<String, Vec<ConstructionRule>>

Construction rules indexed by element name for O(1) lookup HashMap<element_name, Vec<rules_for_that_element>> This avoids linear search through all rules for every element.

default_rule: Option<Value>

Default construction rule (fallback when no specific rule matches)

Implementations

impl ProcessingMode

pub fn new() -> Self

Create a new empty processing mode

pub fn add_rule( &mut self, element_name: String, context: Vec<String>, expr: Value, source_file: Option<String>, source_pos: Option<Position>, )

Add a construction rule

pub fn add_default_rule(&mut self, expr: Value)

Add a default construction rule

pub fn find_match(&self, gi: &str, node: &dyn Node) -> Option<&ConstructionRule>

Find matching rule for an element

Corresponds to OpenJade’s ProcessingMode::findMatch(). Returns the first rule matching the given element name and context.

OPTIMIZATION: Uses HashMap lookup by element name (O(1)) instead of linear search through all rules (O(N)). Critical for large documents!
