ColumnRef

ormkit::query::typed

Struct ColumnRef 

Source 
pub struct ColumnRef<C>
where
    C: Column,
{ /* private fields */ }
Expand description

A typed column reference

This type is returned by column accessor methods on entities (e.g., User::email()). It provides type-safe filter methods based on the column’s type.
