Trait flatdata::VariadicStruct

pub trait VariadicStruct: Clone + Debug + PartialEq + From<(TypeIndex, *const u8)> {
    type ItemBuilder: From<*mut Vec<u8>>;
    fn size_in_bytes(&self) -> usize;
}

A type used as element of MultiArrayView.

Implemented by an enum type.

Associated Types

type ItemBuilder: From<*mut Vec<u8>>

Associated type used for building an item in MultiVector based on this variadic type.

The builder is returned by MultiVector::grow method. It provides convenient methods add_{variant_name} for each enum variant.

Required Methods

fn size_in_bytes(&self) -> usize

Returns size in bytes of the current variant type.

Since a variadic struct can contain types of different sized, this is a method based on the current value type.
