Struct LoweredPage 

pub struct LoweredPage<L: LoweredCalls> { /* private fields */ }

A lowered page and its host, held together by a process that owns both — the bytecode VM’s page, driven from outside the interpreter running the test.

Implementations

impl<L: LoweredCalls> LoweredPage<L>

pub fn new(calls: L) -> Self

Host a page whose engine has not run yet.

pub fn calls(&mut self) -> &mut L

The engine the page runs on.

pub fn unhandled_failure(&self) -> Option<&str>

The first action failure no handler absorbed, if any.

pub fn output(&self) -> String

Every line the page has shown, newline-joined — the engine’s own output convention, so a host that also runs a program’s plain Shows (a ## Main that both prints and drives a page) reports the same text the straight-through compiled path would.

pub fn start( &mut self, auto_mounted: Option<String>, main: impl FnOnce(&mut L) -> Result<(), String>, ) -> Result<(), DriveError>

Start the page: see LoweredHost::start.

pub fn drive(&mut self, d: &Drive) -> Result<(), DriveError>

Carry one driving statement out: see LoweredHost::drive.
