}Expand description
This trait is implemented by types that have a distinct, but optional, body type.
Required Associated Types§
Required Methods§
fn body(&self) -> Option<&Self::Body>
fn body_mut(&mut self) -> Option<&mut Self::Body>
fn set_body(&mut self, body: Self::Body)
fn unset_body(&mut self)
Provided Methods§
fn with_body(self, body: Self::Body) -> Selfwhere
Self: Sized,
fn has_body(&self) -> bool
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
