Trait ToSql 

pub trait ToSql {
    // Required methods
    fn to_sql(&self) -> Result<SqlValue, TypeError>;
    fn sql_type(&self) -> &'static str;
}

Trait for types that can be converted to SQL values.

This trait is implemented for common Rust types to enable type-safe parameter binding in queries.

Required Methods

fn to_sql(&self) -> Result<SqlValue, TypeError>

Convert this value to a SQL value.

fn sql_type(&self) -> &'static str

Get the SQL type name for this value.
