Enum IndexValue 

pub enum IndexValue {
    I64(i64),
    F64(f64),
    Str(Vec<u8>),
}

One indexed scalar. Ordering is total within a type; the catalog guarantees a segment only ever holds one variant.

Variants

I64(i64)

TYPE i64.

F64(f64)

TYPE f64 (never NaN — coercion rejects it).

Str(Vec<u8>)

TYPE str (raw bytes, memcmp order).

Implementations

impl IndexValue

pub fn coerce(ty: ValType, raw: &[u8]) -> Option<IndexValue>

Coerce raw field bytes per the declared type. None = the row is excluded from the index (and counted as a coerce failure).

pub fn parse_literal(ty: ValType, raw: &[u8]) -> Option<IndexValue>

Parse a query-side literal (same rules as Self::coerce).

pub fn approx_bytes(&self) -> usize

Approximate heap bytes (for the memory formula / IDX.LIST).

Trait Implementations

impl Clone for IndexValue

fn clone(&self) -> IndexValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IndexValue

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

Formats the value using the given formatter.

impl Eq for IndexValue

impl Ord for IndexValue

fn cmp(&self, other: &IndexValue) -> 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.

impl PartialEq for IndexValue

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

impl PartialOrd for IndexValue

fn partial_cmp(&self, other: &IndexValue) -> 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.
