Struct Path 

pub struct Path {
    pub root: PathRoot,
    pub projection: Projection,
}

Describes a traversal through fields.

The root is not specified as part of the struct.

Fields

root: PathRoot

Where the path originates from

projection: Projection

Traversal through the fields

Implementations

impl Path

pub fn model(root: impl Into<ModelId>) -> Path

pub fn field(root: impl Into<ModelId>, field: usize) -> Path

pub const fn from_index(root: ModelId, index: usize) -> Path

pub fn from_variant(parent: Path, variant_id: VariantId) -> Path

Creates a path rooted at a specific enum variant.

parent is the path that navigates to the enum field. Subsequent projection steps (appended via chain) index into the variant’s fields using 0-based local indices.

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

pub fn chain(&mut self, other: &Path)

pub fn into_stmt(self) -> Expr

Trait Implementations

impl Clone for Path

fn clone(&self) -> Path

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Path

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

Formats the value using the given formatter.

impl PartialEq for Path

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