Trait SchemaOps 

pub trait SchemaOps {
    // Required method
    fn columns(&self) -> &[ColumnDef];

    // Provided methods
    fn column_index(&self, name: &str) -> Option<usize> { ... }
    fn column(&self, name: &str) -> Option<&ColumnDef> { ... }
    fn primary_key_columns(&self) -> Vec<&ColumnDef> { ... }
    fn len(&self) -> usize { ... }
    fn is_empty(&self) -> bool { ... }
}

Shared schema operations (eliminates duplication between Strict and Columnar).

Required Methods

fn columns(&self) -> &[ColumnDef]

Provided Methods

fn column_index(&self, name: &str) -> Option<usize>

fn column(&self, name: &str) -> Option<&ColumnDef>

fn primary_key_columns(&self) -> Vec<&ColumnDef>

fn len(&self) -> usize

fn is_empty(&self) -> bool

Dyn Compatibility

This trait is dyn compatible.

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