Trait gclient::ext::sp_runtime::codec::DecodeLength

pub trait DecodeLength {
    // Required method
    fn len(self_encoded: &[u8]) -> Result<usize, Error>;
}

Trait that allows the length of a collection to be read, without having to read and decode the entire elements.

Required Methods

fn len(self_encoded: &[u8]) -> Result<usize, Error>

Return the number of elements in self_encoded.

Object Safety

This trait is not object safe.
