Implementations

impl ScalarKind

pub const fn metadata(self) -> ScalarMetadata

Return the full metadata descriptor for one scalar kind.

pub const fn coercion_family(self) -> ScalarCoercionFamily

Return coercion routing family for this scalar kind.

pub const fn is_numeric_value(self) -> bool

Return whether this scalar participates in numeric-valued classification.

pub const fn supports_numeric_coercion(self) -> bool

Return whether this scalar supports numeric widening coercion.

pub const fn supports_arithmetic(self) -> bool

Return whether this scalar supports arithmetic trait derivation.

pub const fn supports_equality(self) -> bool

Return whether this scalar supports equality predicates.

pub const fn supports_ordering(self) -> bool

Return whether this scalar supports ordering predicates.

pub const fn is_keyable(self) -> bool

Return whether this scalar is keyable at query/schema level.

pub const fn is_storage_key_encodable(self) -> bool

Return whether this scalar can be encoded as a storage key.

Trait Implementations

impl Clone for ScalarKind

fn clone(&self) -> ScalarKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScalarKind

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

Formats the value using the given formatter.

impl Hash for ScalarKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ScalarKind

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