Struct JsonFormat 

pub struct JsonFormat {
    pub encoding: Option<JsonEncoding>,
}

The SQL/JSON FORMAT JSON [ENCODING <enc>] specifier (SQL:2016).

The only spellable format is JSON (PostgreSQL rejects FORMAT JSONB at raw parse), so the struct’s mere presence records “FORMAT JSON was written”; the optional encoding is the ENCODING tail. PostgreSQL validates the encoding name against UTF8/UTF16/UTF32 at raw parse (“unrecognized JSON encoding”), so it is a closed JsonEncoding rather than a free identifier.

Fields

encoding: Option<JsonEncoding>

Optional encoding for this syntax.

Trait Implementations

impl Clone for JsonFormat

fn clone(&self) -> JsonFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for JsonFormat

impl Debug for JsonFormat

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for JsonFormat

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for JsonFormat

impl Hash for JsonFormat

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,

impl PartialEq for JsonFormat

fn eq(&self, other: &JsonFormat) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Render for JsonFormat

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

Renders FORMAT JSON [ENCODING <enc>]; callers write the leading space.

fn operand_binding_power(&self) -> Option<BindingPower>

The binding power this node contributes when it appears as an operand, or None (the default) for a self-delimiting node — an atom, call, or constructor — that never needs parentheses.

impl Serialize for JsonFormat

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
