Enum SegmentKind 

#[non_exhaustive]
pub enum SegmentKind {
    Object,
    Nested,
}

How one path level is stored — the only shapes a level can take.

Named SegmentKind to stay clear of the value-kind markers in kind. Non-exhaustive: more container kinds may be added.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Object

A group / to-one-join object: extends the dotted path but is not a nested query boundary (it flattens into the enclosing scope).

Nested

A nested array: a real query/sort boundary that must be wrapped.

Trait Implementations

impl Clone for SegmentKind

fn clone(&self) -> SegmentKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SegmentKind

impl Debug for SegmentKind

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

Formats the value using the given formatter.

impl Eq for SegmentKind

impl PartialEq for SegmentKind

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