Struct IndexModel 

pub struct IndexModel { /* private fields */ }

IndexModel

Runtime-only descriptor for an index used by the executor and stores. Keeps core decoupled from the schema Index shape. Indexing is hash-based over Value equality for all variants. Unique indexes enforce value equality; hash collisions surface as corruption.

Implementations

impl IndexModel

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

Return the stable index name.

pub const fn ordinal(&self) -> u16

Return the stable per-entity index ordinal.

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

Return the backing index store path.

pub const fn fields(&self) -> &'static [&'static str]

Return the canonical index field list.

pub const fn key_items(&self) -> IndexKeyItemsRef

Borrow canonical key-item metadata for this index.

pub const fn has_expression_key_items(&self) -> bool

Return whether this index includes expression key items.

pub const fn is_unique(&self) -> bool

Return whether the index enforces value uniqueness.

pub const fn predicate(&self) -> Option<&'static str>

Return optional schema-declared conditional index predicate text metadata.

Runtime planning and execution treat this as display metadata only.

pub fn predicate_semantics(&self) -> Option<&'static Predicate>

Return the canonical generated conditional index predicate semantics.

pub fn is_prefix_of(&self, other: &Self) -> bool

Whether this index’s field prefix matches the start of another index.

Trait Implementations

impl Clone for IndexModel

fn clone(&self) -> IndexModel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IndexModel

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

Formats the value using the given formatter.

impl Display for IndexModel

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

Formats the value using the given formatter.

impl PartialEq for IndexModel

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