Struct DoStatement 

pub struct DoStatement { /* private fields */ }

A “prepared” Durable Object storage statement: the SQL and nothing else.

sql.exec has no separate prepare that reports parameters or columns, so there is nothing to learn by preparing ahead of time. This exists because sqlx’s Executor::prepare has to return something.

Trait Implementations

impl Clone for DoStatement

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl ColumnIndex<DoStatement> for usize

fn index(&self, statement: &DoStatement) -> Result<usize, Error>

Returns a valid positional index into the row or statement, ColumnIndexOutOfBounds, or, ColumnNotFound.

impl Debug for DoStatement

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Statement for DoStatement

type Database = Do

fn into_sql(self) -> SqlStr

Get the original SQL text used to create this statement.

fn sql(&self) -> &SqlStr

Get the original SQL text used to create this statement.

fn parameters(&self) -> Option<Either<&[DoTypeInfo], usize>>

Get the expected parameters for this statement.

fn columns(&self) -> &[DoColumn]
