Trait recursion::CollapsibleExt

pub trait CollapsibleExt: Collapsible

    Self: Sized,
{
    // Required methods
    fn collapse_frames<Out>(
        self,
        collapse_frame: impl FnMut(<Self::FrameToken as MappableFrame>::Frame<Out>) -> Out
    ) -> Out;

}

Required Methods

fn collapse_frames<Out>( self, collapse_frame: impl FnMut(<Self::FrameToken as MappableFrame>::Frame<Out>) -> Out ) -> Out

Given an instance of this type, collapse it into a single value of type Out by traversing the recursive structure of self, generating frames, and collapsing those frames using some function from Frame<Out> -> Out

fn try_collapse_frames<Out, E>( self, collapse_frame: impl FnMut(<Self::FrameToken as MappableFrame>::Frame<Out>) -> Result<Out, E> ) -> Result<Out, E>

Given an instance of this type, collapse it into a single value of type Result<Out, E> by traversing the recursive structure of self, generating frames, and collapsing those frames using some function from Frame<Out> -> Result<Out, E>
