Trait TryAppendValue

pub trait TryAppendValue<T: StorageTryAppend<I>, I: Encode> {
    // Required method
    fn try_append<LikeI: EncodeLike<I>>(item: LikeI) -> Result<(), ()>;
}

Storage value that is capable of StorageTryAppend.

Required Methods

fn try_append<LikeI: EncodeLike<I>>(item: LikeI) -> Result<(), ()>

This might fail if bounds are not respected.

This trait is not dyn compatible.

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