pub fn cast_to_usize_if_valid(
n: u64,
) -> Result<usize, LengthPrefixExceedsMaxError>Expand description
Cast a decoded length prefix to a usize.
Consensus encoded vectors can be up to 4,000,000 bytes long.
This is a theoretical max since block size is 4 meg wu and minimum vector element is one byte.
§Errors
Errors if n is greater than 4,000,000 or won’t fit in a usize.
