Trait Expr 

pub trait Expr: DynClone {
    // Required methods
    fn kind(&self) -> ExprKind;
    fn expr_type(&self) -> Box<dyn DataType>;
    fn as_any(&self) -> &dyn Any;
}

Required Methods

fn kind(&self) -> ExprKind

fn expr_type(&self) -> Box<dyn DataType>

fn as_any(&self) -> &dyn Any

Implementations

impl dyn Expr

pub fn is_const(&self) -> bool

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
