Struct Replay 

pub struct Replay { /* private fields */ }

Answers calls from a recording. Strict replay answers call n from entry n; keyed replay answers each call from the first unused entry with the same statement and inputs. A call the recording does not hold ends the run.

Implementations

impl Replay

pub fn parse(text: &str, keyed: bool) -> Result<Replay, String>

Trait Implementations

impl Database for Replay

fn execute(&mut self, call: &Call<'_>) -> Result<Outcome, Abandoned>

SELECT INTO, SET, VALUES INTO, INSERT, UPDATE and DELETE, and a dynamic statement that is not a query.

fn prepare(&mut self, call: &Call<'_>) -> Result<Outcome, Abandoned>

Checks a statement string PREPARE names, which then runs through execute or open.

fn open(&mut self, call: &Call<'_>) -> Result<Outcome, Abandoned>

fn fetch(&mut self, call: &Call<'_>) -> Result<Outcome, Abandoned>

One row, or no row at the end.

fn fetch_rows(&mut self, call: &Call<'_>, _: u32) -> Result<Outcome, Abandoned>

Up to rows rows for a rowset FETCH, fewer at the end.

fn insert_rows( &mut self, call: &Call<'_>, _: &[Vec<Value>], _: bool, ) -> Result<Outcome, Abandoned>

A multiple-row INSERT: the INSERT of one row call names, once for each of rows, whose values call.inputs holds one after another. SQLERRD(3) is the rows inserted. ATOMIC undoes them all when one fails; NOT ATOMIC keeps the rest, -253, or -254 when none went in.

fn call(&mut self, call: &Call<'_>) -> Result<Outcome, Abandoned>

CALL of a stored procedure, which a backend that runs none refuses; the answer’s parameters give the arguments as the procedure returns them (numeric::assumptions::CALL_FROM_A_RECORDING).

fn close(&mut self, call: &Call<'_>) -> Result<Outcome, Abandoned>

fn commit(&mut self, call: &Call<'_>) -> Result<Outcome, Abandoned>

fn rollback(&mut self, call: &Call<'_>) -> Result<Outcome, Abandoned>

fn close_all(&mut self) -> Result<(), Abandoned>

Closes every cursor, held ones too, as the end of a CICS task does, so the next task on the same connection finds none open. A backend without cursors of its own has nothing to close.
