Enum VariantRepr 

pub enum VariantRepr {
    External,
    Internal {
        tag: String,
    },
    Adjacent {
        tag: String,
        content: String,
    },
    Untagged,
}

How to represent variant in a data model. Corresponds to the $variant-repr extension.

Variants

External

External tagging: {“variant-name”: {…}}

Internal

Internal tagging: {“type”: “variant-name”, …fields…}

Fields

tag: String

Adjacent

Adjacent tagging: {“type”: “variant-name”, “content”: {…}}

Fields

tag: String

content: String

Untagged

Untagged: try all variants without structure-based matching. This is the default when no $variant-repr is specified.

Implementations

impl VariantRepr

pub fn from_annotation(doc: &EureDocument, node_id: NodeId) -> Option<Self>

Create a VariantRepr from $variant-repr annotation node

Trait Implementations

impl Clone for VariantRepr

fn clone(&self) -> VariantRepr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VariantRepr

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

Formats the value using the given formatter.

impl Default for VariantRepr

fn default() -> VariantRepr

Returns the “default value” for a type.

impl Hash for VariantRepr

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 ParseDocument<'_> for VariantRepr

type Error = ParseError

The error type returned by parsing.

fn parse(ctx: &ParseContext<'_>) -> Result<Self, Self::Error>

Parse a value of this type from the given parse context.

impl PartialEq for VariantRepr

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