Enum LambdaSyntax 

pub enum LambdaSyntax {
    Arrow,
    LambdaKeyword,
}

The syntax style for a lambda function.

Variants

Arrow

Arrow syntax: param -> expr or (param1, param2) -> expr

https://docs.databricks.com/aws/en/sql/language-manual/sql-ref-lambda-functions

Supported, but deprecated in DuckDB: https://duckdb.org/docs/stable/sql/functions/lambda

LambdaKeyword

Lambda keyword syntax: lambda param : expr or lambda param1, param2 : expr

Recommended in DuckDB: https://duckdb.org/docs/stable/sql/functions/lambda

Trait Implementations

impl Clone for LambdaSyntax

fn clone(&self) -> LambdaSyntax

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for LambdaSyntax

impl Debug for LambdaSyntax

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

Formats the value using the given formatter.

impl Eq for LambdaSyntax

impl Hash for LambdaSyntax

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for LambdaSyntax

fn cmp(&self, other: &LambdaSyntax) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for LambdaSyntax

fn eq(&self, other: &LambdaSyntax) -> 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 PartialOrd for LambdaSyntax

fn partial_cmp(&self, other: &LambdaSyntax) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl StructuralPartialEq for LambdaSyntax

impl Visit for LambdaSyntax

fn visit<V>(&self, visitor: &mut V) -> ControlFlow<<V as Visitor>::Break>

where V: Visitor,

Visit this node with the provided Visitor.

impl VisitMut for LambdaSyntax

fn visit<V>(&mut self, visitor: &mut V) -> ControlFlow<<V as VisitorMut>::Break>

where V: VisitorMut,

Mutably visit this node with the provided VisitorMut.
