Trait ProjectExpr 

pub trait ProjectExpr<'a> {
    // Required method
    fn select(&'a self, expr: &SelectOp) -> Result<AnyValue<'a>, RadiateError>;
}

Required Methods

fn select(&'a self, expr: &SelectOp) -> Result<AnyValue<'a>, RadiateError>

Dyn Compatibility

This trait is dyn compatible.

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