Trait Selectable 

pub trait Selectable<T: Table> {
    // Required method
    fn column_names() -> &'static [&'static str];
}

Trait for selecting specific columns from a table.

Implemented for tuples of column types to enable type-safe SELECT queries.

Required Methods

fn column_names() -> &'static [&'static str]

Returns the column names to select.

Dyn Compatibility

This trait is not dyn compatible.

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