Enum PduQueueMode

#[repr(C)]
pub enum PduQueueMode {
    Unlimited = 0,
    Limited = 1,
    Circular = 2,
}

IOCTL queue mode

Variants

Unlimited = 0

Attempt to allocate memory for every event coming in to the receive queue. This queue size can keep growing until the API runs out of allocation memory

Limited = 1

Attempt to allocate a fixed buffer size for events coming into the receive queue. Events are discarded from the receive queue if the buffer is full

Circular = 2

Attempt to allocate a fixed buffer size for events coming into the receive queue. Events overwrite stored events if the buffer is full (Like a circular buffer)

Trait Implementations

impl Clone for PduQueueMode

fn clone(&self) -> PduQueueMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PduQueueMode

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

Formats the value using the given formatter.

impl Ord for PduQueueMode

fn cmp(&self, other: &PduQueueMode) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PduQueueMode

fn eq(&self, other: &PduQueueMode) -> 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 PartialOrd for PduQueueMode

fn partial_cmp(&self, other: &PduQueueMode) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
