Struct IsJson 

pub struct IsJson {
    pub this: Expression,
    pub json_type: Option<String>,
    pub unique_keys: Option<JsonUniqueKeys>,
    pub negated: bool,
}

IS JSON predicate (SQL standard) Checks if a value is valid JSON

Fields

this: Expression

json_type: Option<String>

JSON type: VALUE, SCALAR, OBJECT, or ARRAY (None = just IS JSON)

unique_keys: Option<JsonUniqueKeys>

Key uniqueness constraint

negated: bool

Whether IS NOT JSON

Trait Implementations

impl Clone for IsJson

fn clone(&self) -> IsJson

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IsJson

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for IsJson

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for IsJson

fn eq(&self, other: &IsJson) -> 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 IsJson

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
