Fields§

§int: Option<IntegerType>§align: Option<Align>§pack: Option<Align>§flags: ReprFlags§field_shuffle_seed: u64

The seed to be used for randomizing a type’s layout

Note: This could technically be a [u8; 16] (a u128) which would be the “most accurate” hash as it’d encompass the item and crate hash without loss, but it does pay the price of being larger. Everything’s a tradeoff, a u64 seed should be sufficient for our purposes (primarily -Z randomize-layout)

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
