Enum PathRoot 

pub enum PathRoot {
    Model(ModelId),
    Variant {
        parent: Box<Path>,
        variant_id: VariantId,
    },
}

The root of a path traversal.

A path can originate from a top-level model or from a specific variant of an embedded enum field.

Variants

Model(ModelId)

The path originates from a top-level model.

Variant

The path originates from a specific variant of an embedded enum.

parent navigates to the enum field; subsequent projection steps index into that variant’s fields using 0-based local indices.

Fields

parent: Box<Path>

variant_id: VariantId

Implementations

impl PathRoot

pub fn expect_model(&self) -> ModelId

Returns the ModelId, panicking if this root is a Variant root.

pub fn as_model(&self) -> Option<ModelId>

Returns the ModelId if this is a Model root, or None for a Variant root.

Trait Implementations

impl Clone for PathRoot

fn clone(&self) -> PathRoot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PathRoot

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

Formats the value using the given formatter.

impl PartialEq for PathRoot

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