Struct ColumnMetadata 

pub struct ColumnMetadata {
    pub name: Arc<str>,
    pub var_path: Arc<str>,
    pub logic: Option<LogicId>,
    pub literal: Option<Arc<Value>>,
    pub dependencies: Arc<[String]>,
    pub has_forward_ref: bool,
}

Pre-compiled column metadata computed at parse time (zero-copy design)

Fields

name: Arc<str>

Column name (Arc to avoid clones)

var_path: Arc<str>

Variable path like “$columnName” (pre-computed)

logic: Option<LogicId>

Logic ID if this column has evaluation logic

literal: Option<Arc<Value>>

Literal value if no logic (Arc to share across evaluations)

dependencies: Arc<[String]>

Variable names this column depends on (e.g., [“$other_col”])

has_forward_ref: bool

Whether this column has forward references (computed once)
