Implementations

impl Column

pub fn new(name: &str, col_type: &str) -> Self

Creates a new column, validating name against SQL identifier rules.

Panics

Panics if name fails identifier validation. Column names are always developer-supplied compile-time literals — an invalid name is a bug, not a runtime condition.

pub fn not_null(&mut self) -> &mut Self

pub fn nullable(&mut self) -> &mut Self

pub fn default(&mut self, val: ColumnDefault) -> &mut Self

Sets a safe DEFAULT value using the ColumnDefault enum.

The old &str overload has been removed to prevent DDL injection through unescaped DEFAULT clauses.

pub fn primary(&mut self) -> &mut Self
