Struct datafusion_python::datafusion_sql::unparser::dialect::CustomDialectBuilder

pub struct CustomDialectBuilder { /* private fields */ }

CustomDialectBuilder to build CustomDialect using builder pattern

Examples

Building a custom dialect with all default options set in CustomDialectBuilder::new() but with use_timestamp_for_date64 overridden to true

use datafusion_sql::unparser::dialect::CustomDialectBuilder;
let dialect = CustomDialectBuilder::new()
    .with_use_timestamp_for_date64(true)
    .build();
