regression: unnecessary_lazy_evaluations not triggered on thiserror enum variant

[birkenfeld]

Summary

In stable (1.79.0), unnecessary_lazy_evaluations does not trigger when the value of the closure is a constant error variant in an enum that derives thiserror::Error.

• This was emitting the correct warning on 1.63.0.

Lint Name

unnecessary_lazy_evaluations

Reproducer

I tried this code:

use std::io;
use thiserror::Error;

#[derive(Debug, Error)]
pub enum Error {
    #[error("no devices found")]
    NoDevices,
    #[error(transparent)]
    Io(#[from] io::Error),
}

pub struct Master {}

impl Master {
    pub fn get_info(&self) -> Result<bool, Error> {
        let devices = [false];
        let first_device = devices.first().ok_or_else(|| Error::NoDevices)?;
        Ok(*first_device)
    }
}

I expected to see this happen: (from 1.63.0)

Instead, this happened: no warning
