Implementations

impl GenericValue

pub fn is_bindable_scalar(&self) -> bool

Whether this value can stand as a single SQL parameter, key, or literal: true for the scalar variants, false for Null and the composite Array/Map. The one home for that rule — the Postgres source applies it when binding params, building keys, and inlining literals. Written as an exhaustive match so a new variant cannot be added without classifying it here.

Trait Implementations

impl Clone for GenericValue

fn clone(&self) -> GenericValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GenericValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GenericValue

Deserializes from the same natural shape it serializes to, by inspecting the value’s form rather than expecting serde’s tagged-enum encoding. This requires a self-describing format (JSON, MessagePack, …); it is what lets a compiled config round-trip. A Decimal is written as a string by its serde integration, so a decimal literal round-trips as a String — a documented edge for the rare decimal constant / default.

fn deserialize<D>( deserializer: D, ) -> Result<GenericValue, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for GenericValue

impl Hash for GenericValue

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

where __H: Hasher,

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 GenericValue

fn eq(&self, other: &GenericValue) -> 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 Serialize for GenericValue

Serializes to the natural JSON shape — 5, "x", true, null, […], {…} — not serde’s externally-tagged enum form ({"Int": 5}). This is what makes a serialized Config or IndexMapping read like the data it describes; a value’s variant is evident from its JSON shape.

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
