Struct SortableIndexKey 

pub struct SortableIndexKey {
    pub key: ImmutableRecord,
    pub metadata: Arc<IndexInfo>,
}

Wrapper for index keys that implements collation-aware, ASC/DESC-aware ordering.

Fields

key: ImmutableRecord

The key as bytes.

metadata: Arc<IndexInfo>

Index metadata containing sort orders and collations

Implementations

impl SortableIndexKey

pub fn new_from_bytes(key_bytes: Vec<u8>, metadata: Arc<IndexInfo>) -> Self

pub fn new_from_record(key: ImmutableRecord, metadata: Arc<IndexInfo>) -> Self

pub fn new_from_values( values: Vec<ValueRef<'_>>, metadata: Arc<IndexInfo>, ) -> Result<Self>

pub fn contains_null(&self, num_indexed_cols: usize) -> Result<bool>

Check if the index key contains any NULL values (excluding the rowid column). In SQLite, NULLs don’t violate UNIQUE constraints, so we skip conflict checks for NULL keys.

pub fn matches_prefix(&self, other: &Self, num_cols: usize) -> Result<bool>

Check if the first num_cols columns of this key match another key. Used for UNIQUE index conflict detection where we need to compare only the indexed columns, not the rowid suffix.

Trait Implementations

impl Clone for SortableIndexKey

fn clone(&self) -> SortableIndexKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SortableIndexKey

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

Formats the value using the given formatter.

impl Eq for SortableIndexKey

impl Ord for SortableIndexKey

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for SortableIndexKey

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

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for SortableIndexKey

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
