Trait SqlHost 

pub trait SqlHost<'w, P: Copy, S>: Host<P> {
    // Required methods
    fn session(&mut self) -> Option<&mut Session<'w>>;
    fn in_task(&self) -> bool;
    fn program_id(&self) -> String;
    fn text(&self, text: &S) -> String;
    fn place_pos(&self, place: P) -> Pos;
    fn untyped(&mut self, abend: AbendId) -> Abend;

    // Provided method
    fn locate_indicator(&mut self, place: P) -> Result<Loc, Abend> { ... }
}

What a statement asks of the executor running it beyond Host.

Required Methods

fn session(&mut self) -> Option<&mut Session<'w>>

The run unit’s database session, when one is attached.

fn in_task(&self) -> bool

A CICS task, whose unit of work SYNCPOINT ends rather than EXEC SQL.

fn program_id(&self) -> String

fn text(&self, text: &S) -> String

fn place_pos(&self, place: P) -> Pos

Where a host variable is written, which a program check reading it names.

fn untyped(&mut self, abend: AbendId) -> Abend

The abend a host variable with no SQL type gives when its statement reaches it.

Provided Methods

fn locate_indicator(&mut self, place: P) -> Result<Loc, Abend>

An indicator variable’s storage; an executor whose place for an indicator array named without subscripts is not its first element locates that element here.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
