Struct TransactionId 

pub struct TransactionId(pub u32);

32-bit transaction identifier.

Tuple Fields

0: u32

Implementations

impl TransactionId

pub const FIRST: Self

The first valid transaction ID in a session.

pub const INVALID: Self

Invalid transaction ID (must never be used).

pub const SESSION_LESS: Self

Transaction ID for session-less operations (e.g., GetDeviceInfo before OpenSession).

pub fn next(self) -> Self

Get the next transaction ID, wrapping correctly.

Wraps from 0xFFFFFFFE to 0x00000001 (skipping both 0x00000000 and 0xFFFFFFFF).

Trait Implementations

impl Clone for TransactionId

fn clone(&self) -> TransactionId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransactionId

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

Formats the value using the given formatter.

impl Default for TransactionId

fn default() -> TransactionId

Returns the “default value” for a type.

impl Hash for TransactionId

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 TransactionId

fn eq(&self, other: &TransactionId) -> 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.
