Should the usage of {Option, Result}::expect be avoided to safe memory?

[XOSplicer]

Currently there are a few functions that use {Option, Result}::expect because there is no way to return Option or Result. Examples are LinearMap::{index, index_mut} , Vec::from_iter and IndexMap::index.

AFIK the messages that are associated with them are statically allocated in the data section of the binary and therefore take up space, even if no panic actualy can occure.

As this library is used with microcontrollers, should those strings be removed?
I don't know if rust is smart enough to remove them from the binary by itself.

However some clarity in panic messages would be sacrificed in exchange for it.

These strings can be elided with the proper panic implementation. See rust-lang/rust#44489. You can close this issue.
