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 new( name: &'static str, store: &'static str, fields: &'static [&'static str], unique: bool, ) -> Self

pub const fn new_with_ordinal( ordinal: u16, name: &'static str, store: &'static str, fields: &'static [&'static str], unique: bool, ) -> Self

Construct one index descriptor with one explicit stable ordinal.

pub const fn new_with_predicate( name: &'static str, store: &'static str, fields: &'static [&'static str], unique: bool, predicate: Option<&'static str>, ) -> Self

Construct one index descriptor with an optional conditional predicate.

pub const fn new_with_ordinal_and_predicate( ordinal: u16, name: &'static str, store: &'static str, fields: &'static [&'static str], unique: bool, predicate: Option<&'static str>, ) -> Self

Construct one index descriptor with an explicit stable ordinal and optional predicate.

pub const fn new_with_key_items( name: &'static str, store: &'static str, fields: &'static [&'static str], key_items: &'static [IndexKeyItem], unique: bool, ) -> Self

Construct one index descriptor with explicit canonical key-item metadata.

pub const fn new_with_ordinal_and_key_items( ordinal: u16, name: &'static str, store: &'static str, fields: &'static [&'static str], key_items: &'static [IndexKeyItem], unique: bool, ) -> Self

Construct one index descriptor with an explicit stable ordinal and key-item metadata.

pub const fn new_with_key_items_and_predicate( name: &'static str, store: &'static str, fields: &'static [&'static str], key_items: Option<&'static [IndexKeyItem]>, unique: bool, predicate: Option<&'static str>, ) -> Self

Construct one index descriptor with explicit key-item + predicate metadata.

pub const fn new_with_ordinal_and_key_items_and_predicate( ordinal: u16, name: &'static str, store: &'static str, fields: &'static [&'static str], key_items: Option<&'static [IndexKeyItem]>, unique: bool, predicate: Option<&'static str>, ) -> Self

Construct one index descriptor with full explicit runtime identity metadata.

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.

This string is input-only and must be lowered through the canonical index-predicate boundary before semantic use.

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.
