Attribute

Heading1

# Heading — level 1.

Heading2

## Heading — level 2.

Heading3

### Heading — level 3.

Heading4

#### Heading — level 4.

Heading5

##### Heading — level 5.

Heading6

###### Heading — level 6.

Bold

**bold** / __bold__ text.

Italic

*italic* / _italic_ text.

Link

Link label / link text ([label]). Distinct from Style::Url so the renderer can underline navigable labels without underlining the URL.

Url

Link destination ((url)) and autolinks.

MarkupRaw

Inline `code`, fenced code blocks without an info string, link titles.

Markup

List markers, thematic breaks, blockquote markers, and other markup punctuation.

DiagnosticError

Error-severity diagnostic line.

DiagnosticWarning

Warning-severity diagnostic line.

DiagnosticInfo

Information-severity diagnostic line.

DiagnosticHint

Hint-severity diagnostic line.

DiffAdd

Added line content (+ lines) in a unified diff.

DiffRemove

Removed line content (- lines) in a unified diff.

MessagesTimestamp

A commit SHA (magit-log, magit-blame, magit-rebase’s todo).

MessagesTrace

MessagesDebug

MessagesInfo

MessagesWarn

MessagesError

MagitSha

MagitBranchCurrent

The checked-out branch in a branch list (magit-branch’s * marker + name).

MagitRefDecoration

A ref-decoration list after a log SHA ((HEAD -> main, ...)).

MagitRebaseVerb

A rebase-todo verb (pick/reword/edit/squash/fixup/drop).

MagitAuthor

The author column in magit-blame output.

HelpKey

A key or chord you press (`gr`, `<C-c>g`, `]]`).

HelpCommand

An ex-command you type (`:magit-status`).

HelpAction

An action id (`action:magit-refresh`).

HelpLiteral

Any other inline literal — a path, a filename, a git argument.

InlayHint

Inline virtual text — an LSP inlay hint, or any other leading / trailing text a producer splices into a row without it being in the buffer.

DL.3a: inlay runs used to be painted with a hardcoded Color::Named(DarkGray) in the cells worker, with the run’s style discarded — while inlay.hint had been a registered theme element the whole time. Giving inlays a real style variant is what routes them through the theme like everything else, and it is what lets a producer override the colour per inlay (the listing icons use Style::Element).

Element(ElementId)

A span styled by a registered theme element, named directly.

Every variant above is a closed, editor-owned category, and that is right for concepts the editor itself understands. It cannot work for vocabularies that are open by nature — a per-language file-icon palette has ~50 entries and grows, and a WASM plugin can register a theme element by name but can never add a variant to a Rust enum. Without this, themed highlighting is reachable only by editing core, which makes it impossible for plugins by construction (paramount goal #2).

syntax_element_id returns the id unchanged, so this resolves through exactly the same ResolvedTheme lookup as every builtin category — a theme retunes it by name like any other element.

Carries lattice_theme::ElementId (a u32 newtype), so Style stays Copy and its size is unchanged.

Implementations

impl Style

pub fn fingerprint(self) -> u64

A stable-within-this-process numeric fingerprint, for folding a style into a cache-version hash.

DL.1: this exists because Style stopped being field-less. Consumers used to write style as u64, which the compiler allowed only while every variant was a unit — so adding Style::Element would have broken them silently in spirit (loudly in practice, which is how this was found). Routing them through a named method means the payload is included in the fingerprint: two spans differing only in which registered element they name must not collide, or a theme-element change would leave a stale matrix on screen.
