Attribute macros for stringifying. Probably only useful in unit tests and debugging, but who knows.
Basically these macros allow you to stringify using attribute macros instead of the normal stringify!. Since attribute macros must produce an item. Each macro produces a result! macro which expands to the desired string.
You can stringify just attributes: ```rust use stringifyattr::stringifyattr;
asserteq!(
{
#[stringifyattr(foo)] struct Foo;
result!()
},
"foo"
);
Just items:
rust
use stringifyattr::stringifyitem;
asserteq!(
{
#[stringifyitem(foo)] struct Foo;
result!()
},
"struct Foo;"
);
Or the whole thing:
rust
use stringifyattr::stringifyall;
asserteq!( { #[stringifyall(foo)] struct Foo; result!() }, "#[stringify_all(foo)] struct Foo;" ); ```
Since attribute macros cannot differential being invoked with different delimeters, different attributes are provided: ```rust use stringifyattr::stringifybraces as stringify_all;
asserteq!( { #[stringifyall{foo}] struct Foo; result!() }, "#[stringify_all{foo}] struct Foo;" ); ```
Note that these attributes still produce the text "stringify_all" in the output.
