Struct MagitHunkSyntaxHighlight 

pub struct MagitHunkSyntaxHighlight;

Syntax-highlight the code inside a diff, with the + / - colouring layered over it. On by default.

Turning it off gives the flat per-line colouring magit had before — every added line one green, every removed line one red — and skips the tree-sitter parse each hunk otherwise costs. The parse runs off the actor thread and is bounded by the hunk, not the file, so this is an aesthetic switch rather than a performance one for all but the largest diffs.

Read per refresh, not at buffer open, so :set takes effect on the next gr rather than only on reopen — the same contract magit.hunk.context-lines has.

Implementations

impl MagitHunkSyntaxHighlight

pub fn build_spec() -> Option<bool>

Build the runtime spec for this declaration. Used by the registry’s self-registration boot path; not generally called by hand. Direct construction of Option<T> is the macro’s internal-only path – consumer code uses config.get_typed::<#name_ident>() to read and config.set_typed::<#name_ident>(...) to write.

Trait Implementations

impl HasGroup for MagitHunkSyntaxHighlight

const GROUP_NAME: &'static str = <lattice_config::Magit as ::lattice_config::OptionGroup>::NAME

Group display name ("editor", "lsp", …). The macro pulls this from the group = SomeGroup; directive at the declaration block’s head.

impl OptionDecl for MagitHunkSyntaxHighlight

const NAME: &'static str = MagitHunkSyntaxHighlight

Public display name. Boundary-facing only – :set <NAME>=…, TOML keys, completion candidates, :describe-option. Internal access is type-driven. The macro derives this from the option’s identifier (with namespace prefix when declared via mode_options!); manually-typed NAMEs are not supported for built-in options.

const DOC: &'static str = MagitHunkSyntaxHighlight

Doc string. Shown in :describe-option, the :customize form’s per-row help, and :apropos results.

const CUSTOMIZABLE: bool = true

Customize-visibility flag. true (the default) ⇒ option appears in :set autocomplete + the :customize group view. false ⇒ plugin / engine-internal state, hidden from user surfaces. Equivalent of emacs’s defvar vs defcustom. (See mode-architecture.md §6.5.3.)

type Value = bool

The runtime value type. bool, i64, String, plus any domain enum that impls [OptionType].

fn default_value() -> Self::Value

Default value. Returned by a function (rather than a const) so non-const-constructible types like String can be defaults.

fn type_id() -> TypeId

where Self: Sized,

TypeId of the declaration type itself. Hot-path key for the registry’s type-driven storage. Default impl works for every concrete impl.
