Required Methods

fn field_if<T>( &mut self, name: &str, value: &T, pred: impl FnOnce(&T) -> bool, ) -> &mut Self

where T: Debug,

fn field<T>(&mut self, name: &str, value: &T) -> &mut Self

where T: Debug,

fn field_bool( &mut self, value: bool, name_true: &str, name_false: &str, ) -> &mut Self

Provided Methods

fn field_if_not_default<T>(&mut self, name: &str, value: &T) -> &mut Self

where T: Debug + Default + PartialEq,

fn field_if_false(&mut self, name: &str, value: bool) -> &mut Self

fn field_if_true(&mut self, name: &str, value: bool) -> &mut Self

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
