Struct UUID4

#[repr(C)]
pub struct UUID4 { /* private fields */ }

Represents a pseudo-random UUID (universally unique identifier) version 4 based on a 128-bit label as specified in RFC 4122.

Implementations

impl UUID4

pub fn new() -> Self

Creates a new UUID4 instance.

Generates a new UUID version 4, which is based on random or pseudo-random numbers. The UUID is stored as a fixed-length C string byte array.

pub fn to_cstr(&self) -> &CStr

Converts the UUID4 to a C string reference.

Trait Implementations

impl Clone for UUID4

fn clone(&self) -> UUID4

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UUID4

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for UUID4

fn default() -> Self

Creates a new default UUID4 instance.

The default UUID4 is simply a newly generated UUID version 4.

impl<'de> Deserialize<'de> for UUID4

fn deserialize<D>(_deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for UUID4

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<&str> for UUID4

fn from(value: &str) -> Self

Creates a UUID4 from a string slice.

Panics

This function panics:

• If the value string is not a valid UUID.

impl From<String> for UUID4

fn from(value: String) -> Self

Creates a UUID4 from a string.

Panics

This function panics:

• If the value string is not a valid UUID.

impl FromStr for UUID4

fn from_str(s: &str) -> Result<Self, Self::Err>

Attempts to create a UUID4 from a string representation.

The string should be a valid UUID in the standard format (e.g., “6ba7b810-9dad-11d1-80b4-00c04fd430c8”).

type Err = Error

The associated error which can be returned from parsing.

impl Hash for UUID4

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl IntoPy<Py<PyAny>> for UUID4

fn into_py(self, py: Python<'_>) -> PyObject

Performs the conversion.

impl PartialEq for UUID4

fn eq(&self, other: &UUID4) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PyClass for UUID4

type Frozen = False

Whether the pyclass is frozen.

impl PyClassImpl for UUID4

const IS_BASETYPE: bool = false

#[pyclass(subclass)]

const IS_SUBCLASS: bool = false

#[pyclass(extends=…)]

const IS_MAPPING: bool = false

#[pyclass(mapping)]

const IS_SEQUENCE: bool = false

#[pyclass(sequence)]

type BaseType = PyAny

Base class

type ThreadChecker = SendablePyClass<UUID4>

This handles following two situations:

type PyClassMutability = <<PyAny as PyClassBaseType>::PyClassMutability as PyClassMutability>::MutableChild

Immutable or mutable

type Dict = PyClassDummySlot

Specify this class has #[pyclass(dict)] or not.

type WeakRef = PyClassDummySlot

Specify this class has #[pyclass(weakref)] or not.

type BaseNativeType = PyAny

The closest native ancestor. This is PyAny by default, and when you declare #[pyclass(extends=PyDict)], it’s PyDict.

fn items_iter() -> PyClassItemsIter

fn doc(py: Python<'_>) -> PyResult<&'static CStr>

Rendered class doc

impl PyTypeInfo for UUID4

const NAME: &'static str = "UUID4"

Class name.

const MODULE: Option<&'static str> = _

Module name, if any.

fn type_object_raw(py: Python<'_>) -> *mut PyTypeObject

Returns the PyTypeObject instance for this type.

fn type_object_bound(py: Python<'_>) -> Bound<'_, PyType>

Returns the safe abstraction over the type object.

fn is_type_of_bound(object: &Bound<'_, PyAny>) -> bool

Checks if object is an instance of this type or a subclass of this type.

fn is_exact_type_of_bound(object: &Bound<'_, PyAny>) -> bool

Checks if object is an instance of this type.
