pub struct ToMap {
    pub this: Box<Expression>,
}

ToMap - Materialize-style map constructor Can hold either:

• A SELECT subquery (MAP(SELECT ‘a’, 1))
• A struct with key=>value entries (MAP[‘a’ => 1, ‘b’ => 2])

Fields

Either a Select subquery or a Struct containing PropertyEQ entries

Trait Implementations

impl Clone for ToMap

fn clone(&self) -> ToMap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ToMap

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ToMap

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ToMap

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
