Trait truncate_slice_debug::TruncateSliceDebug

pub trait TruncateSliceDebug<'a, T>where
    T: Debug,{
    fn truncate_debug(&self, max_len: usize) -> TruncatedSlice<'a, T>;
}

Required Methods

fn truncate_debug(&self, max_len: usize) -> TruncatedSlice<'a, T>

For a collection of T, return a TruncatedSlice struct with a Debug implementation to only print max_len items
