Advanced element query/polling interfaces for the thirtyfour crate.

These interfaces are currently experimental and will likely be merged into the main thirtyfour crate once they are stable.

If you can help by testing these and providing feedback that would be appreciated.

Usage

ElementQuery

First, import the following:

use thirtyfour_query::{ElementPoller, ElementQueryable};

Next, set the default polling behaviour:

// Disable implicit timeout in order to use new query interface.
driver.set_implicit_wait_timeout(Duration::new(0, 0)).await?;

let poller = ElementPoller::TimeoutWithInterval(Duration::new(20, 0), Duration::from_millis(500));
driver.config_mut().set("ElementPoller", poller)?;

Other ElementPoller options are also available, such as NoWait and NumTriesWithInterval. These can be overridden on a per-query basis as needed.

Now, using the query interface you can do things like:

let elem_text = 
    driver.query(By::Css("thiswont.match")).or(By::Id("searchInput")).first().await?;

This will execute both queries once per poll iteration and return the first one that matches. You can also filter on one or both match arms like this:

driver.query(By::Css("thiswont.match")).with_text("testing")
    .or(By::Id("searchInput")).with_class("search").and_not_enabled()
    .first().await?;

To fetch all matching elements instead of just the first one, simply change first() to all() and you'll get a Vec instead.

ElementQuery also allows the user of custom predicates that take a &WebElement argument and return a WebDriverResult<bool>.

ElementWaiter

First, import the following:

use thirtyfour_query::{ElementPoller, ElementWaitable};

Next, set the default polling behaviour (same as for ElementQuery - the same polling settings are used for both):

// Disable implicit timeout in order to use new query interface.
driver.set_implicit_wait_timeout(Duration::new(0, 0)).await?;

let poller = ElementPoller::TimeoutWithInterval(Duration::new(20, 0), Duration::from_millis(500));
driver.config_mut().set("ElementPoller", poller)?;

Now you can do things like this:

elem.wait_until().displayed().await?;
// You can optionally provide a nicer error message like this.
elem.wait_until().error("Timed out waiting for element to disappear").not_displayed().await?;

elem.wait_until().enabled().await?;
elem.wait_until().clickable().await?;

And so on. See the ElementWaiter docs for the full list of predicates available.

ElementWaiter also allows the user of custom predicates that take a &WebElement argument and return a WebDriverResult<bool>.

A range of pre-defined predicates are also supplied for convenience in the thirtyfour_query::conditions module.

use thirtyfour_query::conditions;

elem.wait_until().conditions(vec![
    conditions::element_is_displayed(true),
    conditions::element_is_clickable(true)
]).await?;

Take a look at the conditions module for the full list of predicates available. NOTE: Predicates require you to specify whether or not errors should be ignored.

These predicates (or your own) can also be supplied as filters to ElementQuery.
