Fields

return_addresses: bool

Should return addresses be authenticated?

auth_traps: bool

Do authentication failures cause a trap?

indirect_gotos: bool

Do indirect goto label addresses need to be authenticated?

elf_got: bool

Should ELF GOT entries be signed?

aarch64_jump_table_hardening: bool

Use hardened lowering for jump-table dispatch?

function_pointers: Option<PointerAuthSchema>

The ABI for C function pointers.

init_fini: Option<PointerAuthSchema>

The ABI for function addresses in .init_array and .fini_array

intrinsics: bool

Use of pointer authentication intrinsics.

typeinfo_vt_ptr_discrimination: bool

The following are used only for compatibility with C++ and control over generated abi version. They do not control Rust code generation.

vt_ptr_addr_discrimination: bool

vt_ptr_type_discrimination: bool

Implementations

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.
