Struct ElfDylib

pub struct ElfDylib { /* private fields */ }

An unrelocated dynamic library

Implementations

impl ElfDylib

pub fn easy_relocate<'iter, 'scope, 'find, 'lib, S, F>( self, scope: S, pre_find: &'find F, ) -> Result<RelocatedDylib<'lib>>

where S: Iterator<Item = &'iter RelocatedDylib<'scope>> + Clone, F: Fn(&str) -> Option<*const ()>, 'scope: 'iter, 'iter: 'lib, 'find: 'lib,

Relocate the dynamic library with the given dynamic libraries and function closure.

Note

During relocation, the symbol is first searched in the function closure pre_find.

pub fn relocate<'iter, 'scope, 'find, 'lib, S, F, D>( self, scope: S, pre_find: &'find F, deal_unknown: D, local_lazy_scope: Option<Box<dyn for<'a> Fn(&'a str) -> Option<*const ()> + 'static>>, ) -> Result<RelocatedDylib<'lib>>

where S: Iterator<Item = &'iter RelocatedDylib<'scope>> + Clone, F: Fn(&str) -> Option<*const ()>, D: Fn(&ElfRela, &ElfDylib, S) -> bool, 'scope: 'iter, 'iter: 'lib, 'find: 'lib,

Relocate the dynamic library with the given dynamic libraries and function closure.

Note

• During relocation, the symbol is first searched in the function closure pre_find.
• The deal_unknown function is used to handle relocation types not implemented by efl_loader or failed relocations
• Typically, the scope should also contain the current dynamic library itself, relocation will be done in the exact order in which the dynamic libraries appear in scope.
• When lazy binding, the symbol is first looked for in the global scope and then in the local lazy scope
