lower_bound in BTreeMap

[KiaShakiba]

Any plans to support the lower_bound function in BTreeMap?

It should be quite easy to do. I'll get to it by next week.

Great! Thanks!

I saw that rust-lang/rust#107540 is still very much in discussion, so it's quite unlikely that it will come out anytime soon.

Nonetheless, the design of Cursor, not mut, seems to be fixed, so I will only release lower_bound in 0.3.0, to avoid a major release.
