Struct ExprInList 

pub struct ExprInList {
    pub expr: Box<Expr>,
    pub list: Box<Expr>,
}

Tests whether a value is contained in a list.

Returns true if expr equals any item in list. Returns false for an empty list.

Examples

in_list(x, [1, 2, 3])  // returns `true` if x is 1, 2, or 3
in_list(x, [])         // returns `false`

Fields

expr: Box<Expr>

The value to search for.

list: Box<Expr>

The list to search within.

Trait Implementations

impl Clone for ExprInList

fn clone(&self) -> ExprInList

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExprInList

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

Formats the value using the given formatter.

impl From<ExprInList> for Expr

fn from(value: ExprInList) -> Expr

Converts to this type from the input type.

impl PartialEq for ExprInList

fn eq(&self, other: &ExprInList) -> 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.
