Struct Metadata

pub struct Metadata {
    pub semantic: Option<String>,
    pub fluent: Option<String>,
    pub usage: Option<String>,
    pub note: Option<String>,
}

Optional free-form annotations a theme author can attach to any slot. The runtime ignores these — inspection tools (and human readers of the JSON) use them.

All fields are optional and default to None. Missing fields in the JSON do not raise an error.

Fields

semantic: Option<String>

Canonical name of the token in the design system (e.g. "primary/500").

fluent: Option<String>

Equivalent name in another system (e.g. "NeutralColors.white" for Fluent). Useful when migrating from or cross-referencing other kits.

usage: Option<String>

Human-readable guidance on where to use this slot.

note: Option<String>

Free-form note, typically for quirks worth flagging in the JSON.

Trait Implementations

impl Clone for Metadata

fn clone(&self) -> Metadata

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Metadata

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Metadata

fn default() -> Metadata

Returns the “default value” for a type.

impl PartialEq for Metadata

fn eq(&self, other: &Metadata) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
