Struct VariantConstraint 

pub struct VariantConstraint {
    pub union_path: Vec<PathSegment>,
    pub variant: String,
    pub requires_explicit_tag: bool,
}

Constraint for style applicability under a union branch.

Fields

union_path: Vec<PathSegment>

Path to the union node whose variant selection constrains this rule.

variant: String

Variant name that must be selected.

requires_explicit_tag: bool

Whether this branch requires an explicit variant tag.

Trait Implementations

impl Clone for VariantConstraint

fn clone(&self) -> VariantConstraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VariantConstraint

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

Formats the value using the given formatter.

impl PartialEq for VariantConstraint

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