Struct Json 

pub struct Json<T>(pub T);

Wrapper for a schema-declared Json column’s Rust field type. See the module docs for why this exists instead of sqlx::types::Json<Value>.

Serialize/Deserialize stay #[serde(transparent)] — delegating straight to T’s own impl (for T = Value, untagged since cratestack#506) — so the model struct’s HTTP/RPC wire representation is unchanged from before this fix. The jsonb column codec below (sqlx::Type / Encode / Decode, used for the Postgres bind/ row-decode path, never for the wire format) is untagged too; that’s the actual cratestack#162 fix, scoped to on-disk storage and independent of Value’s own serde impls.

Implementations

impl<T> Json<T>

pub fn into_inner(self) -> T

Trait Implementations

impl<T: Clone> Clone for Json<T>

fn clone(&self) -> Json<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Json<T>

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

Formats the value using the given formatter.

impl<'r> Decode<'r, Postgres> for Json<Value>

fn decode(value: PgValueRef<'r>) -> Result<Self, BoxDynError>

Decode a new value of this type using a raw value from the database.

impl<T: Default> Default for Json<T>

fn default() -> Json<T>

Returns the “default value” for a type.

impl<T> Deref for Json<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T> DerefMut for Json<T>

fn deref_mut(&mut self) -> &mut T

Mutably dereferences the value.

impl<'de, T> Deserialize<'de> for Json<T>

where T: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'q> Encode<'q, Postgres> for Json<Value>

fn encode_by_ref( &self, buf: &mut PgArgumentBuffer, ) -> Result<IsNull, BoxDynError>

Writes the value of self into buf without moving self.

fn encode( self, buf: &mut <DB as Database>::ArgumentBuffer, ) -> Result<IsNull, Box<dyn Error + Send + Sync>>

where Self: Sized,

Writes the value of self into buf in the expected format for the database.

fn produces(&self) -> Option<<DB as Database>::TypeInfo>

fn size_hint(&self) -> usize

impl<T> From<T> for Json<T>

fn from(value: T) -> Self

Converts to this type from the input type.

impl<T: PartialEq> PartialEq for Json<T>

fn eq(&self, other: &Json<T>) -> 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 PgHasArrayType for Json<Value>

fn array_type_info() -> PgTypeInfo

fn array_compatible(ty: &PgTypeInfo) -> bool

impl<T> Serialize for Json<T>

where T: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<T: PartialEq> StructuralPartialEq for Json<T>

impl Type<Postgres> for Json<Value>

fn type_info() -> PgTypeInfo

Returns the canonical SQL type for this Rust type.

fn compatible(ty: &PgTypeInfo) -> bool

Determines if this Rust type is compatible with the given SQL type.
