All fields start at no offset. The usize
is the field count.
In the case of primitives the number of fields is 0
.

Array/vector-like placement, with all fields of identical types.

Struct-like placement, with precomputed offsets.
Fields are guaranteed to not overlap, but note that gaps
before, between and after all the fields are NOT always
padding, and as such their contents may not be discarded.
For example, enum variants leave a gap at the start,
where the discriminant field in the enum layout goes.
Fields of Arbitrary
offsets: Vec<Size> | 🔬 This is a nightly-only experimental API. (rustc_private )this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?
Offsets for the first byte of each field,
ordered to match the source definition order.
This vector does not go in increasing order.

memory_index: Vec<u32> | 🔬 This is a nightly-only experimental API. (rustc_private )this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?
Maps source order field indices to memory order indices,
depending how fields were permuted.

Create an error for a missing method specialization. Defaults to panicking with type, trait & method names. S
is the encoder/decoder state type, T
is the type being encoded/decoded, and the arguments are the names of the trait and method that should've been overridden. Read more
