Enum LabelForm 

pub enum LabelForm {
    Canonical,
    Stripped,
    Shortcut,
    Community,
}

How the user spelled a label site, relative to the resolved canonical.

Forward-looking infrastructure for the label namespace model described in comms/specs/general.lex §4. The eventual contract: Lex accepts up to three spellings of any lex.* label and one spelling of any community label, and round-trips the user’s choice so lexd format does not silently rewrite the source.

Status in this PR (#584 PR 1/5): the enum and the form field on Label exist; the parse-time NormalizeLabels stage tags labels that match its legacy-rewrite table, defaulting to Canonical for every other site. No formatter consults form yet — lexd format still emits label.value verbatim. PR 2 expands NormalizeLabels into the full resolution rules (universal prefix-strip, Community classification, hard-error for doc.* and unrecognized bare); PR 3 wires form through the formatter so the roundtrip promise lands end-to-end.

Variants

Canonical

User wrote the canonical form verbatim (lex.metadata.author). This is also the default when a Label is constructed programmatically without a specific source form (e.g. from the wire codec, where the wire always carries the canonical).

Stripped

User wrote the prefix-stripped form (metadata.author). Resolves to canonical by prepending lex..

Shortcut

User wrote the one-segment shortcut (author). Resolves to canonical via the normative shortcut table.

Community

User wrote a community label (acme.task). Carries a single accepted spelling and round-trips unchanged. Registry validation is deferred to the analysis stage.

Trait Implementations

impl Clone for LabelForm

fn clone(&self) -> LabelForm

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LabelForm

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

Formats the value using the given formatter.

impl Default for LabelForm

fn default() -> Self

Returns the “default value” for a type.

impl Hash for LabelForm

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for LabelForm

fn eq(&self, other: &LabelForm) -> 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.
