Struct LambdaExpr 

pub struct LambdaExpr {
    pub parameters: Vec<Identifier>,
    pub body: Expression,
    pub colon: bool,
    pub parameter_types: Vec<Option<DataType>>,
}

Lambda expression

Fields

parameters: Vec<Identifier>

body: Expression

colon: bool

True if using DuckDB’s LAMBDA x : expr syntax (vs x -> expr)

parameter_types: Vec<Option<DataType>>

Optional type annotations for parameters (Snowflake: a int -> a + 1) Maps parameter index to data type

Trait Implementations

impl Clone for LambdaExpr

fn clone(&self) -> LambdaExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LambdaExpr

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LambdaExpr

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for LambdaExpr

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
