Struct Path 

pub struct Path { /* private fields */ }

A path value used to locate objects in layers or scenegraphs.

Implementations

impl Path

pub const fn empty_path() -> Self

The empty path value.

pub const fn absolute_root_path() -> Self

The absolute path representing the top of the namespace hierarchy.

pub const fn reflexive_relative_path() -> Self

The relative path representing “self”.

pub fn is_empty(&self) -> bool

Returns true if this path is the Path::empty_path.

pub fn is_absolute_root(&self) -> bool

Returns true if this path is the Path::absolute_root_path.

pub fn append_child(&self, child_name: &Token) -> Self

Creates a path by appending an element for child_name to this path.

This path must be a prim path, the AbsoluteRootPath or the ReflexiveRelativePath.

pub fn append_property(&self, prop_name: &Token) -> Self

Creates a path by appending an element for prop_name to this path.

This path must be a prim path or the ReflexiveRelativePath.

pub fn append_variant_selection(&self, variant_set: &str, variant: &str) -> Self

Creates a path by appending an element for variant_set and variant to this path.

This path must be a prim path.

pub fn append_target(&self, target_path: &Path) -> Self

Creates a path by appending an element for target_path to this path.

This path must be a prim property or relational attribute path.

pub fn append_relational_attribute(&self, attr_name: &Token) -> Self

Creates a path by appending an element for attr_name to this path.

This path must be a target path.

pub fn append_mapper(&self, target_path: &Path) -> Self

Creates a path by appending an element for target_path to this path.

This path must be a prim property or relational attribute path.

pub fn append_mapper_arg(&self, arg_name: &Token) -> Self

Creates a path by appending an element for arg_name to this path.

This path must be a mapper path.

pub fn append_expression(&self) -> Self

Creates a path by appending an expression element to this path.

This path must be a prim property or relational attribute path.

pub fn parent_path(&self) -> Self

Return the path that identifies this path’s namespace parent.

pub fn name(&self) -> String
