Struct WebExecutor 

pub struct WebExecutor;

Available on crate feature web only.

Web-based executor implementation for WASM targets.

This executor uses wasm-bindgen-futures::spawn_local to execute futures in web environments. Both Send and non-Send futures are handled the same way since web environments are single-threaded.

Panic Handling

Unlike other executors, the web executor cannot catch panics due to WASM limitations. If a spawned task panics, the entire WASM module will terminate. This is a fundamental limitation of the WASM environment and cannot be worked around.

Implementations

impl WebExecutor

pub fn new() -> Self

Create a new WebExecutor.
