pub unsafe trait Key: Copy + Eq {
// Required methods
fn into_usize(self) -> usize;
fn try_from_usize(int: usize) -> Option<Self>;
}Expand description
Types implementing this trait can be used as keys for all Rodeos
§Safety
into/from must be perfectly symmetrical, any key that goes on must be perfectly reproduced with the other
Required Methods§
Sourcefn into_usize(self) -> usize
fn into_usize(self) -> usize
Returns the usize that represents the current key
Sourcefn try_from_usize(int: usize) -> Option<Self>
fn try_from_usize(int: usize) -> Option<Self>
Attempts to create a key from a usize, returning None if it fails
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
