Struct SqlitePreparedStatement 

pub struct SqlitePreparedStatement { /* private fields */ }

Handle to a prepared SQLite statement owned by a worker connection.

Instances can be cloned and reused across awaited calls. Dropping the handle simply releases the reference; the underlying connection will keep the statement cached via rusqlite’s internal prepare_cached mechanism.

Implementations

impl SqlitePreparedStatement

pub async fn query( &self, params: &[RowValues], ) -> Result<ResultSet, SqlMiddlewareDbError>

Execute the prepared statement as a query and materialise the rows into a ResultSet.

Errors

Returns SqlMiddlewareDbError if the underlying worker fails to execute the statement or if result conversion encounters an issue.

pub async fn execute( &self, params: &[RowValues], ) -> Result<usize, SqlMiddlewareDbError>

Execute the prepared statement as a DML (INSERT/UPDATE/DELETE) returning rows affected.

Errors

Returns SqlMiddlewareDbError if the worker cannot execute the statement or if the result cannot be converted into the expected row count.

pub fn sql(&self) -> &str

Access the raw SQL string of the prepared statement.
