Struct quackdb_internal::statement::PreparedStatementHandle

pub struct PreparedStatementHandle { /* private fields */ }

Implementations

impl PreparedStatementHandle

Safety

• All parameter indices must be in range

pub unsafe fn from_raw( raw: duckdb_prepared_statement, parent: Arc<ConnectionHandle> ) -> Arc<Self>

Safety

Takes ownership

pub unsafe fn destroy(&mut self)

Safety

Does not consider utilization. Normally, let Rust handle this automatically.

pub fn nparams(&self) -> u64

pub unsafe fn param_type(&self, param_idx: u64) -> TypeId

Safety

• param_idx must be in range
