Struct JumpTable 

pub struct JumpTable {
    pub lib: PathBuf,
    pub map: AddressMap,
    pub aslr_reference: u64,
    pub new_base_address: u64,
    pub ifunc_count: u64,
}

One patch: the library holding the new code and the old -> new address map into it.

Fields

lib: PathBuf

The patch dylib, a path the platform loader can open directly.

map: AddressMap

Old function address -> new function address, both as link-time addresses: neither the running binary’s ASLR slide nor the patch’s load address is applied yet (apply_patch rebases both sides).

aslr_reference: u64

Link-time address of the running binary’s main, the anchor that recovers its ASLR slide.

new_base_address: u64

Link-time address of the patch library’s main, the anchor that recovers its load address.

ifunc_count: u64

Indirect-function count; only a wasm loader reads it, kept so the wire shape is identical.
