Required Methods§
fn static_addr_of( &self, cv: Self::Value, align: Align, kind: Option<&str> ) -> Self::Value
fn codegen_static(&self, def_id: DefId)
sourcefn add_used_global(&self, global: Self::Value)
fn add_used_global(&self, global: Self::Value)
Mark the given global value as “used”, to prevent the compiler and linker from potentially removing a static variable that may otherwise appear unused.
sourcefn add_compiler_used_global(&self, global: Self::Value)
fn add_compiler_used_global(&self, global: Self::Value)
Same as add_used_global(), but only prevent the compiler from potentially removing an otherwise unused symbol. The linker is still permitted to drop it.
This corresponds to the documented semantics of the #[used]
attribute, although
on some targets (non-ELF), we may use add_used_global
for #[used]
statics
instead.
