Macro macro_state::clear_state

clear_state!() { /* proc-macro */ }

Clears the value for the specified key, if it exists.

If an error occurs while trying to clear the state file for the specified key, the error will surface as a compile-time error.

Example

write_state!("my key", "test");
read_state!("my key"); // => "test"
clear_state!("my key");
has_state!("my key"); // => false
