LazyRuntime

Struct LazyRuntime 

Source
pub struct LazyRuntime<Arch: RelocationArch> { /* private fields */ }
Expand description

Public facade over Relink’s lazy binding runtime state.

This handle lets custom lazy binders inspect PLT relocation context and reuse Relink’s symbol lookup / jump-slot writeback without exposing the internal core runtime layout.

Implementations§

Source§

impl<Arch: RelocationArch> LazyRuntime<Arch>

Source

pub unsafe fn from_runtime(runtime: VmAddr) -> Self

Rebuilds a lazy runtime handle from a context entry passed to a resolver.

§Safety

runtime must be a value previously returned by Self::runtime for a live module with the same Arch type.

Source

pub fn runtime(&self) -> VmAddr

Returns the native resolver context entry for this runtime handle.

Source

pub fn memory(&self) -> &dyn ImageMemory

Returns the mapped image memory owned by the module.

Source

pub fn plt_relocation(&self, rela_idx: usize) -> Option<LazyPltReloc<'_, Arch>>

Returns one PLT relocation by lazy relocation index.

Source

pub fn lookup_symbol( &self, symbol: SymbolEntry<'_, Arch::Layout>, ) -> Result<Option<VmAddr>>

Looks up a symbol through Relink’s normal lazy binding lookup path.

Source

pub fn write_jump_slot( &self, reloc: &LazyPltReloc<'_, Arch>, value: VmAddr, ) -> Result<()>
where <Arch::Layout as ElfLayout>::Word: ByteRepr,

Writes a resolved address into the relocation’s jump slot.

Source

pub fn resolve_default(&self, rela_idx: usize) -> Result<Option<VmAddr>>
where <Arch::Layout as ElfLayout>::Word: ByteRepr,

Performs Relink’s default lazy binding flow and writes the jump slot.
