Doorbell Event TRB

Implementations

impl Doorbell

pub fn into_raw(self) -> [u32; 4]

Returns the wrapped array.

pub fn cycle_bit(self) -> bool

Returns the Cycle bit bit.

pub fn set_cycle_bit(&mut self) -> &mut Self

Sets the Cycle bit bit.

pub fn clear_cycle_bit(&mut self) -> &mut Self

Clears the Cycle bit bit.

impl Doorbell

pub fn new() -> Self

This method sets the sets the value of the TRB Type field properly. All the other fieldds are set to 0.

impl Doorbell

pub fn completion_code(&self) -> Result<CompletionCode, u8>

Returns the Completion Code.

Errors

This method may return an Err value with the Completion Code that is either reserved or not implemented by this crate.

impl Doorbell

pub fn db_reason(self) -> u8

Returns the value of the DB Reason field.

pub fn vf_id(self) -> u8

Returns the value of the VF ID field.

pub fn slot_id(self) -> u8

Returns the value of the Slot ID field.

Trait Implementations

impl AsRef<[u32]> for Doorbell

fn as_ref(&self) -> &[u32]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Doorbell

fn clone(&self) -> Doorbell

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Doorbell

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

Formats the value using the given formatter.

impl Default for Doorbell

fn default() -> Self

Returns the “default value” for a type.

impl From<Doorbell> for [u32; 4]

fn from(t: Doorbell) -> Self

Converts to this type from the input type.

impl From<Doorbell> for Allowed

fn from(v: Doorbell) -> Self

Converts to this type from the input type.

impl Hash for Doorbell

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 Ord for Doorbell

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Doorbell> for Doorbell

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

impl PartialOrd<Doorbell> for Doorbell

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl TryFrom<[u32; 4]> for Doorbell

type Error = [u32; 4]

The type returned in the event of a conversion error.

fn try_from(raw: [u32; 4]) -> Result<Self, Self::Error>

Performs the conversion.
