Trait IsBody

pub trait IsBody:
    Sized
    + Debug
    + Clone
    + 'static {
    // Required method
    fn body<'tcx, S: UnderOwnerState<'tcx>>(did: RDefId, s: &S) -> Option<Self>;

    // Provided method
    fn from_mir<'tcx, S: UnderOwnerState<'tcx>>(
        _s: &S,
        _body: Body<'tcx>,
    ) -> Option<Self> { ... }
}

Required Methods

fn body<'tcx, S: UnderOwnerState<'tcx>>(did: RDefId, s: &S) -> Option<Self>

Provided Methods

fn from_mir<'tcx, S: UnderOwnerState<'tcx>>( _s: &S, _body: Body<'tcx>, ) -> Option<Self>

Reuse a MIR body we already got. Panic if that’s impossible.

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.
