Macro rust_icu_common::generalized_fallible_setter [−][src]
macro_rules! generalized_fallible_setter { ($top_level_method_name:ident, $impl_name:ident, [ $( $arg:ident : $arg_type:ty, )* ]) => { ... }; }
Expand description
Expands into a setter methods that forwards all its arguments between []’s and returns a Result<(), common::Error>.
The invocation:
ⓘ
impl _ { generalized_fallible_setter!( get_context, unum_getContext, [context_type: sys::UDisplayContextType, ] ); }
allows us to bind the function:
UDisplayContext unum_setContext(
const SOMETYPE* t,
UDisplayContext value,
UErrorCode* status
);
which then becomes:
ⓘ
impl _ { fn set_context(&self, value: sys::UDisplayContext) -> Result<(), common::Error>; }
where Self
has an internal representation named exactly Self::rep
.
