Enum BlockKind 

pub enum BlockKind {
    Paragraph(Text),
    Heading {
        level: u8,
        text: Text,
    },
    Bullet(Text),
    Ordered {
        number: u64,
        text: Text,
    },
    Task {
        checked: bool,
        text: Text,
    },
    Quote {
        kind: Option<QuoteKind>,
        text: Text,
    },
    Code {
        language: Option<String>,
        code: Text,
    },
    Image {
        url: String,
        alt: Text,
        width: Option<u32>,
    },
    Bookmark {
        url: String,
        form: Form,
    },
    Table {
        align: Vec<Align>,
        header: Vec<Text>,
        rows: Vec<Vec<Text>>,
    },
    Rule,
}

The block vocabulary. Closed by design — a consumer that needs a block of its own is a reason to widen this enum rather than to grow an extension system.

Variants

Paragraph(Text)

Heading

Fields

level: u8

1–6.

text: Text

Bullet(Text)

Ordered

Fields

number: u64

The rendered number. Stored rather than derived so a list starting at 3 survives the round trip.

text: Text

Task

Fields

checked: bool

text: Text

Quote

A blockquote. kind is the GFM alert it opens with — see QuoteKind.

Fields

kind: Option<QuoteKind>

text: Text

Code

The code carries a Text like every other editable region, so one accessor and one edit path cover the whole document. Its marks are unreachable rather than forbidden: nothing that writes here creates one.

Fields

language: Option<String>

code: Text

Image

The caption is the alt text — markdown has one slot, and a reader that cannot see the picture reads the same words. Like BlockKind::Code’s, its marks are unreachable rather than forbidden.

Fields

url: String

alt: Text

width: Option<u32>

A drag off the handle in bezel-editor, in whole pixels — None is the natural width. u32 rather than a float: this derives Eq, and a f32 cannot because of NaN. Spelled ![alt|480](url), which leaves the title slot to say what a title says.

Bookmark

A link with a block to itself, painted richly. Atomic on purpose: everything it shows past the URL comes from crate::preview, so there is nothing here for a caret to edit.

Form picks which of the three — a chip, a card, or a card with its picture across the width. Off a line of its own the same link is a Mark::Mention, which is the same three minus what shaped text cannot hold.

Fields

url: String

form: Form

Table

Fields

align: Vec<Align>

header: Vec<Text>

rows: Vec<Vec<Text>>
