Struct diesel::pg::types::sql_types::Json

pub struct Json;

The JSON SQL type. This type can only be used with feature = "serde_json"

Normally you should prefer Jsonb instead, for the reasons discussed there.

ToSql impls

• serde_json::Value

FromSql impls

• serde_json::Value

Trait Implementations

impl<'expr> AsExpression<Json> for &'expr Value

type Expression = Bound<Json, Self>

The expression being returned

fn as_expression(self) -> Self::Expression

Perform the conversion

impl<'expr2, 'expr> AsExpression<Json> for &'expr2 &'expr Value

type Expression = Bound<Json, Self>

The expression being returned

fn as_expression(self) -> Self::Expression

Perform the conversion

impl AsExpression<Json> for Value

type Expression = Bound<Json, Self>

The expression being returned

fn as_expression(self) -> Self::Expression

Perform the conversion

impl FromSql<Json, Pg> for Value

fn from_sql(bytes: Option<&[u8]>) -> Result<Self>

See the trait documentation.

impl ToSql<Json, Pg> for Value

fn to_sql<W: Write>(&self, out: &mut Output<W, Pg>) -> Result

See the trait documentation.

impl QueryId for Json

type QueryId = Json

A type which uniquely represents Self in a SQL query.

const HAS_STATIC_QUERY_ID: bool

HAS_STATIC_QUERY_ID: bool = true

Can the SQL generated by Self be uniquely identified by its type?

fn query_id() -> Option<TypeId>

Returns the type id of Self::QueryId if Self::HAS_STATIC_QUERY_ID. Returns None otherwise.

impl NotNull for Json

impl SingleValue for Json

impl HasSqlType<Json> for Pg

fn metadata(_: &PgMetadataLookup) -> PgTypeMetadata

Fetch the metadata for the given type

fn row_metadata(
    out: &mut Vec<Self::TypeMetadata>,
    lookup: &Self::MetadataLookup
)

Fetch the metadata for a tuple representing an entire row

impl Debug for Json

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Clone for Json

fn clone(&self) -> Json

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Json

impl Default for Json

fn default() -> Json

Returns the "default value" for a type.
