insert builder supports values from iterator

[brahmlower]

PR Info

Hey again! 👋

The InsertStatement builder doesn't seem to support adding a dynamic number of items without breaking the functional pattern exhibited throughout the docs. I went ahead and added a method for it since it was pretty simple and was a nice quality of life feature.

Though I've got a PR here, there are a few points that I'd like to ask about:

• [ ] I'm not sure I've chosen a good name for the function. If you have any suggestions or preferences for a better name, please let me know and I can update the PR.

• [ ] The method I've added wraps .values_panic, but I've not added an equivalent method for wrapping .values. I wasn't sure what behavior would be expected of such a function, so I figured I should ask first. The two options I see are:

  • proceeds on Ok and early exits on first Err

    pub fn values_from<I>(&mut self, values_iter: impl IntoIterator<Item = I>) -> Result<&mut Self>
    where
    I: IntoIterator<Item = SimpleExpr>,
    {

  • continues iterating when .values returns an Err, but collects the failing items and their errors so that all failures can be returned. I thought briefly about what this interface might look like but I'm not really sure (not sure if that means it's just a bad idea? 😅 )

New Features

• [ ] Added the values_from_panic method to InsertStatement for adding multiple rows at once from something that implements IntoIterator.

  let rows = vec![
    [2.1345.into(), "24B".into()],
    [5.15.into(), "12A".into()],
  ];
  
  let query = Query::insert()
    .into_table(Glyph::Table)
    .columns([Glyph::Aspect, Glyph::Image])
    .values_from_panic(rows)
    .to_owned();
