Struct LoweredHost 

pub struct LoweredHost { /* private fields */ }

The host state a browser keeps for a lowered page. It owns no engine: every statement it carries out borrows the engine the page runs on for exactly that statement (LoweredHost::drive).

Implementations

impl LoweredHost

pub fn new() -> Self

The host of a page that has not started.

pub fn of_page(page: Option<String>) -> Self

The host of a program whose ## Page component page names (None for a program that mounts nothing by itself): what its reload mounts again, and what Replay runs against before any Mount of the test’s own.

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

The first action failure no handler absorbed, if any.

pub fn take_unhandled_failure(&mut self) -> Option<String>

The first action failure no handler absorbed, taken — the program’s own failure once the program that hosts the page has finished.

pub fn unhandled_failure_site(&self) -> Option<u32>

Where the first unabsorbed failure happened, when the engine tracks it.

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

Start the page on calls: its main runs — the mount a ## Page performs by itself, and whatever else the program does at the top level — and the page settles. A failing main is the program’s failure. auto_mounted names the ## Page component the program mounts by itself, if any (crate::page_host::auto_mounted_page_component) — set before main runs, since a page’s own mount is not a Drive::Mount this host ever sees.

pub fn settle<L: LoweredCalls + ?Sized>(&mut self, calls: &mut L)

Deliver a popstate the page is owed and complete every request that has an answer — what the host does after anything runs in the page (Driver::settle).

pub fn drive<L: LoweredCalls + ?Sized>( &mut self, calls: &mut L, d: &Drive, ) -> Result<(), DriveError>

Carry one driving statement out on the page calls runs, exactly as the browser host would, then settle.
