Oxidized Kilo

A reimplementation of the Kilo tutorial in Rust.

Implementation notes:

• The editor prefix has been removed from all the editor methods. Since this implementation uses impls on a shared Editor struct, the prefix is redundant
• Any C equivalent functionality based on memory allocating/deallocating, or other manual book-keeping is instead implemented in a more idiomatic Rust fashion.
• Row structs are referenced by their index in the Editor struct, rather than as a direct reference in method calls. This generally simplifies dealing with the rules of Rust (borrow checker).
• The prompt method of the editor can not take an arbitrary formatting string, due to Rust requiring a string literal for string formatting macros.

Additions / Changes

• Reverse coloring for search results, so comment types can have different colors
• Two separate vectors are used to define the two types of keywords, rather than the weird pipe suffix
