From the example code

let pear: Optionfruit::Model = Fruit::find_by_id(28).one(db).await?;

// Into ActiveModel
let mut pear: fruit::ActiveModel = pear.unwrap().into();

// Update name attribute
pear.name = Set("Sweet pear".to_owned());

// Update corresponding row in database using primary key value
let pear: fruit::Model = pear.update(db).await?;
<<<<
How do I check if the pear.update(db) failed?

eg the example code is not protected by a transaction so if another thread deleted the pear between the find and the update then I assume the update would fail, but I'm not sure how to check for this.

Basically, I was looking for an equivalent to the DeleteResult where I can check rows_affected.

Thanks.
