Function decode_rlp_integer_partial 

pub fn decode_rlp_integer_partial<'a>(
    input: &'a [u8],
    accumulator: &mut DecodeAccumulator,
) -> Result<RlpInteger<'a>, DecodeError>

Decodes one canonical RLP integer from the start of input.

Warning: this intentionally accepts trailing bytes. Use decode_rlp_integer when the full input must be consumed.

The input-length budget check applies to the full input slice, not only the consumed integer bytes. Callers that decode from a larger outer buffer must pre-slice before calling this helper.
