Struct Variant

pub struct Variant {
    pub span: Span,
    pub attr_info: AttrInfo,
    pub name: String,
    pub fields: Vector<FieldId, Field>,
    pub discriminant: ScalarValue,
}

Fields

span: Span

attr_info: AttrInfo

name: String

fields: Vector<FieldId, Field>

discriminant: ScalarValue

The discriminant used at runtime. This is used in remove_read_discriminant to match up SwitchInt targets with the corresponding Variant.

Implementations

impl Variant

pub fn renamed_name(&self) -> &str

The new name for this variant, as suggested by the #[charon::rename] and #[charon::variants_prefix] attributes.

pub fn is_opaque(&self) -> bool

Whether this variant has a #[charon::opaque] annotation.

Trait Implementations

impl AstVisitable for Variant

fn drive<V: VisitAst>(&self, v: &mut V) -> ControlFlow<V::Break>

Recursively visit this type with the provided visitor. This calls the visitor’s visit_$any method if it exists, otherwise visit_inner.

fn drive_mut<V: VisitAstMut>(&mut self, v: &mut V) -> ControlFlow<V::Break>

Recursively visit this type with the provided visitor. This calls the visitor’s visit_$any method if it exists, otherwise visit_inner.

fn name(&self) -> &'static str

The name of the type, used for debug logging.

fn dyn_visit<T: AstVisitable>(&self, f: impl FnMut(&T))

Visit all occurrences of that type inside self, in pre-order traversal.

fn dyn_visit_mut<T: AstVisitable>(&mut self, f: impl FnMut(&mut T))

Visit all occurrences of that type inside self, in pre-order traversal.

impl Clone for Variant

fn clone(&self) -> Variant

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Variant

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Variant

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Variant

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

Formats the value using the given formatter.

impl<'s, V> Drive<'s, V> for Variant

where V: Visitor + Visit<'s, Span> + Visit<'s, Vector<FieldId, Field>> + Visit<'s, ScalarValue>,

fn drive_inner(&'s self, visitor: &mut V) -> ControlFlow<V::Break>

Call v.visit() on the immediate contents of self.

impl<'s, V> DriveMut<'s, V> for Variant

where V: Visitor + VisitMut<'s, Span> + VisitMut<'s, Vector<FieldId, Field>> + VisitMut<'s, ScalarValue>,

fn drive_inner_mut(&'s mut self, visitor: &mut V) -> ControlFlow<V::Break>

Call v.visit() on the immediate contents of self.

impl<C: AstFormatter> FmtWithCtx<C> for Variant

fn fmt_with_ctx(&self, ctx: &C) -> String

fn fmt_with_ctx_and_indent(&self, _tab: &str, _ctx: &C) -> String

fn with_ctx<'a>(&'a self, ctx: &'a C) -> impl Display + 'a

Returns a struct that implements Display. This allows the following:

impl Serialize for Variant

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
