Struct ModifyOp 

pub struct ModifyOp {
    pub delete_templates: Vec<TripleTemplate>,
    pub insert_templates: Vec<TripleTemplate>,
    pub where_clause: Box<LogicalOperator>,
    pub graph: Option<String>,
}

SPARQL MODIFY operation (DELETE/INSERT WHERE).

Per SPARQL 1.1 Update spec, this operator:

1. Evaluates the WHERE clause once to get bindings
2. Applies DELETE templates using those bindings
3. Applies INSERT templates using the SAME bindings

This ensures DELETE and INSERT see consistent data.

Fields

delete_templates: Vec<TripleTemplate>

DELETE triple templates (patterns with variables).

insert_templates: Vec<TripleTemplate>

INSERT triple templates (patterns with variables).

where_clause: Box<LogicalOperator>

WHERE clause that provides variable bindings.

graph: Option<String>

Named graph context (for WITH clause).
