Struct Formatting 

pub struct Formatting {
    pub mode: Mode,
    pub marks: Vec<Mark>,
    pub block: Option<SharedString>,
    pub fenceable: bool,
}

What a toolbar reads to light itself, in one call.

Every field is a question a bar asks on every frame, and each was a separate reach into the document before: which marks are lit, what the block is called, whether cmd-E would fence, and whether any of it applies at all. Taken together so a bar cannot answer half of them from one frame and half from the next.

Fields

mode: Mode

Which form the document is in. In Mode::Source the markup is already spelled out, so Self::marks is empty and a bar has nothing to light.

marks: Vec<Mark>

The marks the selection carries throughout — and at a collapsed caret, the ones the next character typed would carry, cmd-B before typing included.

block: Option<SharedString>

What the caret’s block is called in turns, or None for a block the menu does not offer.

fenceable: bool

Whether Mark::Code here makes a fence out of the selection rather than an inline span — the one chord whose meaning changes with what is selected, and the one a bar cannot work out for itself.
