Struct CachedPlanRef

Source

pub struct CachedPlanRef {
    pub statement: Arc<Statement>,
    pub has_params: bool,
    pub param_count: usize,
    pub compiled: Arc<RwLock<CompiledExecution>>,
}

Expand description

Lightweight reference to a cached plan for query execution. Contains only what’s needed to execute: the immutable statement and param info.

Fields§

§statement: Arc<Statement>

The parsed AST (cheap Arc clone)

§has_params: bool

Whether this query has parameter placeholders

§param_count: usize

Number of parameters required

§compiled: Arc<RwLock<CompiledExecution>>

Shared reference to compiled execution state (lazily populated)
