Trait ScalarOps 

pub trait ScalarOps {
    // Required methods
    fn match_col_ref(&self) -> Option<usize>;
    fn references(&self, col_ref: usize) -> bool;
}

Required Methods

fn match_col_ref(&self) -> Option<usize>

If this expression is a column-reference, return the column referenced.

fn references(&self, col_ref: usize) -> bool

Returns true if this expression is a reference to the given column.

Dyn Compatibility

This trait is dyn compatible.

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