pub struct PropertyId(/* private fields */);
Expand description
Unique ID of a property implementation.
§Memory
The internal number is a NonZeroU32
, that means that
Option<PropertyId>
and
PropertyId
are the same size as u32
.
§As Hash
The generated internal number has good statistical distribution and can be used as its own hash,
although it is not cryptographically safe, as it is simply a sequential counter scrambled using a modified
splitmix64
.
§Static
The unique ID cannot be generated at compile time, but you can use the static_id!
macro to declare
a lazy static that instantiates the ID.
Implementations§
source§impl PropertyId
impl PropertyId
sourcepub fn new_unique() -> Self
pub fn new_unique() -> Self
Generates a new unique ID.
sourcepub fn sequential(self) -> u32
pub fn sequential(self) -> u32
Un-scramble the underlying value to get the original sequential count number.
If two IDs, id0
and id1
where generated by the same thread then id0.sequential() < id1.sequential()
.
sourcepub fn from_raw(raw: u32) -> Self
pub fn from_raw(raw: u32) -> Self
Creates an ID from a raw value.
The value must not be zero, panics if it is, the value must have been provided by get
otherwise
the ID will not be unique.
sourcepub fn from_sequential(num: u32) -> Self
pub fn from_sequential(num: u32) -> Self
Creates an ID from a sequential
number.
§Safety
The value must not be zero, panics if it is, the value must have been provided by sequential
otherwise
the ID will not be unique.
