ACP: Chars::take_str

[dev-ardi]

Proposal

A fn in Chars<'a> that skips until it finds a specific char and returns the &'a str while it was skipping.

For example:

"I like bananas"
    ^ Chars is here 

let subslice = my_chars.take_str(' ');
assert_eq(subslice, "like");
"I like bananas"
          ^ Chars is here 

Problem statement

There's currently no ergonomic way of doing this, it's possible but not something that feels supported.

Motivating examples or use cases

While iterating over chars it's not the most ergonomic thing to find individual words, or to get subslices.

Solution sketch

fn take_str(&mut self) -> &str

Please fill out the motivation section more. I would like to see a real example of its use.

It also looks like your prose description of its behavior doesn't match the behavior shown in your code snippet.
