Expand description
SQL Generator – converts an AST back into SQL strings.
The central type is Generator, which walks an Expression tree and
emits a SQL string. Generation is controlled by a GeneratorConfig that
specifies the target dialect, formatting preferences, identifier quoting
style, function name casing, and many other dialect-specific flags.
For one-off generation the static helpers Generator::sql and
Generator::pretty_sql are the simplest entry points. For repeated
generation, construct a Generator once with Generator::with_config
and call Generator::generate for each expression.
