Multiple applicable provide methods in scope

[dtolnay]

#![feature(error_generic_member_access, provide_any)]

use thiserror::Error;
use std::error::Error;

#[derive(Error, Debug)]
#[error("...")]
struct MyError {
    #[source]
    #[backtrace]
    x: std::io::Error,
}

//use std::any::Provider;

This compiles, but if you uncomment the Provider import, it fails because both Error and Provider contain a method named provide (I consider this a flaw in the standard library API... rust-lang/rust#99301 rust-lang/rust#96024).
