pub struct Defective<'a, R> { /* private fields */ }

A backend with one Defect injected. The wrapped backend does the work.

Implementations

impl<'a, R: RelationalBackend> Defective<'a, R>

pub fn new(inner: &'a R, defect: Defect) -> Self

Wrap inner so it is wrong in exactly the way defect says.

Trait Implementations

impl<'a, R: Debug> Debug for Defective<'a, R>

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

Formats the value using the given formatter.

impl<R: RelationalBackend> RelationalBackend for Defective<'_, R>

type Tx<'a> = DefectiveTx<'a, R> where Self: 'a

A transaction on this backend. Dropping it without commit rolls it back.

fn backend(&self) -> &str

The backend’s name as it appears in matrix rows (postgres).

fn version(&self) -> &str

The server version string as it appears in matrix rows (16.15).

fn dialect(&self) -> Dialect

The dialect statements must be written in.

async fn execute(&self, sql: &str, params: &[Value]) -> Result<u64, RelError>

Run a statement that returns no rows; the result is the number of rows affected.

async fn query(&self, sql: &str, params: &[Value]) -> Result<Vec<Row>, RelError>

Run a statement and return its rows.

async fn begin(&self) -> Result<DefectiveTx<'_, R>, RelError>

Begin a transaction.
