Enum Sentinel 

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

Discriminator for a Card.

The document frontmatter carries QUILL: <ref> and is the document-level main card; every composable card carries a kind — written as the ```card <kind> info string (canonical) or a legacy CARD: <kind> sentinel. Sentinel captures that distinction in the typed model so every card is one uniform shape.

Variants

Main(QuillReference)

The document entry card, carrying the QUILL reference.

Card(String)

A composable card with the given kind 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 From<&Sentinel> for SentinelV0_81_0

fn from(sentinel: &Sentinel) -> Self

Converts to this type from the input type.

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.

impl TryFrom<SentinelV0_81_0> for Sentinel

type Error = StorageError

The type returned in the event of a conversion error.

fn try_from(sentinel: SentinelV0_81_0) -> Result<Self, Self::Error>

Performs the conversion.
