Enum NamedShapePathKey

pub enum NamedShapePathKey {
    Field(String),
    AnyField,
    Index(usize),
    AnyIndex,
}

NamedShapePathKey represents a single step in a subpath associated with a ShapeCase::Name shape reference. When pretty-printed, these subpaths are delimited by . characters (with "..."-quoting as necessary for non-identifier field names), and can be either ::Field names or array ::Index values.

As a special form of catch-all ::Index value, the step may also be the wildcard ::AnyIndex, which denotes a union of all the element shapes of an array, or just the given shape if not an array, which is useful to support GraphQL-like array mapping. When pretty-printed, these wildcard keys look like .*, and if multiple wildcards are used in a row, they will be coalesced/simplified down to just one logical .*.

impl From<&str> for NamedShapePathKey

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<String> for NamedShapePathKey

fn from(value: String) -> Self

Converts to this type from the input type.

impl PartialEq for NamedShapePathKey

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