Netrw Cheatsheet (Vim's File Browser)

See also:

• vinegar.vim, which makes - open netrw in the directory of the current file, with the cursor on the current file (and pressing - again goes up a directory). Vinegar also hides a bunch of junk that's normally at the top of netrw windows, changes the default order of files, and hides files that match wildignore.

  With vinegar, . in netrw opens Vim's command line with the path to the file under the cursor at the end of the command. ! does the same but also prepends ! at the start of the command. y. copies the absolute path of the file under the cursor. ~ goes to your home dir. Ctrl+6 goes back to the file (buffer) that you had open before you opened netrw.

To launch netrw:

My explanation of the main concepts in Rust

There are three main concepts with Rust:

1. Ownership (only one variable "owns" the data at one time, and the owner is in charge of deallocating)
2. Borrowing (you can borrow a reference to an owned variable)
3. Lifetimes (all data keeps track of when it will be destroyed)

These are fairly simple concepts, but they are often counter-intuitive to concepts in other languages, so I wanted to give a shot at
