Struct UUID4 

pub struct UUID4 { /* private fields */ }

Represents a Universally Unique Identifier (UUID) 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.

The UUID value is stored as a fixed-length C string byte array.

pub fn from_bytes(bytes: [u8; 16]) -> Self

Creates a UUID4 from raw 16-byte representation.

Sets the version-4 nibble and the RFC 4122 variant bits before constructing, so any 16 bytes produce a valid v4 UUID.

pub fn to_cstr(&self) -> &CStr

Converts the UUID4 to a C string reference.

Panics

Panics if the internal byte array is not a valid C string (does not end with a null terminator).

pub fn as_str(&self) -> &str

Returns the UUID as a string slice.

Panics

Never panics in practice: the stored byte representation is constructed from valid ASCII UUID strings by UUID4::new or deserialization paths.

pub fn as_bytes(&self) -> [u8; 16]

Returns the raw UUID bytes (16 bytes).

This method is optimized for serialization where the UUID bytes are needed directly without string conversion overhead.

Panics

Never panics in practice: the stored byte representation is a valid UTF-8 UUID v4 string produced by UUID4::new or deserialization paths.

Trait Implementations

fn clone(&self) -> UUID4

Returns a duplicate of the value.

fn from(value: String) -> Self

Converts to this type from the input type.

fn from(value: UUID4) -> Self

Creates a uuid::Uuid from a UUID4.

impl From<Uuid> for UUID4

fn from(value: Uuid) -> Self

impl<'a, 'py> FromPyObject<'a, 'py> for UUID4

where Self: Clone,

type Error = PyClassGuardError<'a, 'py>

The type returned in the event of a conversion error.

fn extract( obj: Borrowed<'a, 'py, PyAny>, ) -> Result<Self, <Self as FromPyObject<'a, 'py>>::Error>

Extracts Self from the bound smart pointer obj.

impl FromStr for UUID4

fn from_str(value: &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., “2d89666b-1a1e-4a75-b193-4eb3b454c757”).

Errors

Returns an error if the value is not a valid UUID version 4 RFC 4122.

type Err = String

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,

impl<'py> IntoPyObject<'py> for UUID4

type Target = UUID4

The Python output type

type Output = Bound<'py, <UUID4 as IntoPyObject<'py>>::Target>

fn into_pyobject( self, py: Python<'py>, ) -> Result<<Self as IntoPyObject<'_>>::Output, <Self as IntoPyObject<'_>>::Error>

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.

Description of how this class is laid out in memory

type BaseType = PyAny

Base class

type ThreadChecker = NoopThreadChecker

This handles following two situations:

type Inventory = Pyo3MethodsInventoryForUUID4

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.
