Rust Tips & Suggestions

Struct forms:

There are three struct forms: unit structs, tuple structs, and named field structs:

struct UnitStruct;
struct TupleStruct(String, usize);
struct NamedStruct { string: String, is_cuss_word: bool }

Update: line breaking and view revisions

So I had a frustrating week, last week. I'd been spending much of december working on a long-standing feature for xi, line breaking / word wrap. That is; the ability to wrap lines of text to the width of the window, as needed. This is table stakes for a text editor (or a text view, or a web browser, or anything that displays text in a variable width window) but it's something we had until now only half-done.


This problem has some nuance. To back up: We have a string, and we have a width (of a window, say), and we need to determine how to break the string up so that it fits in the given window. To do this, we need to know two things at runtime: where in the string we are allowed to create a line break (the break opportunities), and the width required to draw various 'atoms' of the string, where an 'atom' is a sub-string that cannot contain a line break.
