Struct wnf::GUID

pub struct GUID(/* private fields */);

A Globally Unique Identifier (GUID)

This is used to (optionally) specify type IDs for states. It provides From<T> implementations for various types T from foreign crates that also represent GUIDs. These implementations are available when the respective Cargo features are enabled:

• Feature windows: From<windows::core::GUID>
• Feature winapi: From<winapi::shared::guiddef::GUID>
• Feature uuid: From<uuid::Uuid>

Implementations

impl GUID

pub fn new() -> Result<Self>

Creates a unique GUID value

Errors

Returns an error if creating the GUID fails

pub const fn zeroed() -> Self

Creates a GUID represented by the all-zero byte pattern

pub const fn from_values( data1: u32, data2: u16, data3: u16, data4: [u8; 8] ) -> Self

Creates a GUID with the given constant values

pub const fn from_u128(uuid: u128) -> Self

Creates a GUID from a u128 value

pub const fn to_u128(&self) -> u128

Converts a GUID to a u128 value

Trait Implementations

impl Clone for GUID

fn clone(&self) -> GUID

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GUID

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

Formats the value using the given formatter.

impl Default for GUID

fn default() -> GUID

Returns the “default value” for a type.

impl From<&str> for GUID

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<GUID> for GUID

Available on crate feature windows only.

fn from(guid: GUID) -> Self

Converts to this type from the input type.

impl From<GUID> for GUID

Available on crate feature winapi only.

fn from(guid: GUID) -> Self

Converts to this type from the input type.

impl From<GUID> for GUID

Available on crate feature winapi only.

fn from(guid: GUID) -> Self

Converts to this type from the input type.

impl From<GUID> for GUID

Available on crate feature windows only.

fn from(guid: GUID) -> Self

Converts to this type from the input type.

impl From<GUID> for Uuid

Available on crate feature uuid only.

fn from(guid: GUID) -> Self

Converts to this type from the input type.

impl From<GUID> for u128

fn from(value: GUID) -> Self

Converts to this type from the input type.

impl From<Uuid> for GUID

Available on crate feature uuid only.

fn from(uuid: Uuid) -> Self

Converts to this type from the input type.

impl From<u128> for GUID

fn from(value: u128) -> Self

Converts to this type from the input type.

impl Hash for GUID

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 PartialEq for GUID

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

This method tests for self and other values to be equal, and is used by ==.

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

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