Enum PathStep 

pub enum PathStep {
    Field(u32),
    Index(u32),
    Variant(u32),
    MapKey,
    MapValue,
    OptionSome,
    Deref,
}

A single step in a path through a type structure.

Each step records an index that can be used to navigate back through a Shape to reconstruct field names and types.

Variants

Field(u32)

Navigate to a struct field by index

Index(u32)

Navigate to a list/array element by index

Variant(u32)

Navigate to an enum variant by index

MapKey

Navigate into a map key

MapValue

Navigate into a map value

OptionSome

Navigate into Some of an Option

Deref

Navigate through a pointer/reference

Trait Implementations

impl Clone for PathStep

fn clone(&self) -> PathStep

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PathStep

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

Formats the value using the given formatter.

impl PartialEq for PathStep

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