Enum IndexKeyItem 

pub enum IndexKeyItem {
    Field(&'static str),
    Expression(IndexExpression),
}

IndexKeyItem

Canonical index key-item metadata. Field preserves field-key behavior. Expression reserves deterministic expression-key identity metadata.

Variants

Field(&'static str)

Expression(IndexExpression)

Implementations

impl IndexKeyItem

pub const fn field(&self) -> &'static str

Borrow this key-item’s referenced field.

pub fn canonical_text(&self) -> String

Render one deterministic canonical text form for diagnostics/display.

Trait Implementations

impl Clone for IndexKeyItem

fn clone(&self) -> IndexKeyItem

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IndexKeyItem

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

Formats the value using the given formatter.

impl PartialEq for IndexKeyItem

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