Implementations

impl Parameter

pub fn to_sql_literal(&self) -> Result<String, QueryError>

Convert parameter to SQL literal string.

This is a basic implementation for Phase 1. In production, use proper prepared statement protocol.

impl Clone for Parameter

fn clone(&self) -> Parameter

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Parameter

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
