Trait Implementations

impl Clone for SessionBuilderConfig

fn clone(&self) -> SessionBuilderConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SessionBuilderConfig

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

Formats the value using the given formatter.

impl Default for SessionBuilderConfig

Manual implementation of Default to ensure proper initialization of output_format This struct requires explicit default value for output_format field

fn default() -> Self

Returns the “default value” for a type.
