}

Trait for fields, that has unknown compile-time size. Usually important for arrays, or other types that in rust is always at HEAP

Required Methods

fn item_size() -> Offset

size of item fixed part that this Field collect.

fn count(&self) -> Offset

count of items in collection

unsafe fn from_buffer(buffer: &'a [u8], from: Offset, count: Offset) -> Self

create collection from buffer

fn extend_buffer(&self, buffer: &mut Vec<u8>)

extend buffer with this collection

fn check_data(
    buffer: &'a [u8],
    from: CheckedOffset,
    count: CheckedOffset,
    latest_segment: CheckedOffset
) -> Result

check collection data
