Struct Recorder 

pub struct Recorder<'w> { /* private fields */ }

Writes every call and its answer while inner answers.

Implementations

impl<'w> Recorder<'w>

pub fn new( inner: Box<dyn Database + 'w>, out: Box<dyn Write + 'w>, source: &str, ) -> Result<Self>

source names what answered, and goes in the recording’s header.

Trait Implementations

impl Database for Recorder<'_>

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

SELECT INTO, SET, VALUES INTO, INSERT, UPDATE and DELETE.

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

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

One row, or no row at the end.

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

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

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

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.
