Trait Extractable 

pub trait Extractable: Sized {
    // Required method
    fn extract_from(
        node: &NodeHandle,
    ) -> impl Future<Output = Result<Self, ExtractionError>> + Send;
}

Types that can be extracted from a live DOM crate::page::NodeHandle.

Implement this manually or derive it with #[derive(Extract)].

Example

use stygian_browser::extract::{Extractable, ExtractionError, Extract};
use stygian_browser::page::NodeHandle;

#[derive(Extract)]
struct Title {
    text: String,
}

// `PageHandle::extract_all::<Title>`.

Required Methods

fn extract_from( node: &NodeHandle, ) -> impl Future<Output = Result<Self, ExtractionError>> + Send

Extract an instance of Self from the given DOM node.

Errors

Returns an error when a required selector matches no element, when a CDP call fails, or when nested extraction fails.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
