Enum Sentinel 

pub enum Sentinel {
    Main(QuillReference),
    Card(String),
}

Discriminator for a Card’s metadata fence.

The first fence in a Quillmark document carries QUILL: <ref> and is the document-level main card; every subsequent fence carries CARD: <tag> and is a composable card. Sentinel captures that distinction in the typed model so every fence is one uniform shape.

Variants

Main(QuillReference)

QUILL: <ref> — the document entry card.

Card(String)

CARD: <tag> — a composable card with the given tag.

Implementations

impl Sentinel

pub fn as_str(&self) -> String

String form of this sentinel’s value: the quill reference for Main, the tag for Card.

pub fn is_main(&self) -> bool

Returns true if this is a Main sentinel.

Trait Implementations

impl Clone for Sentinel

fn clone(&self) -> Sentinel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Sentinel

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

Formats the value using the given formatter.

impl PartialEq for Sentinel

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