Struct RxFlags

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

Flags set by a Device when handing a buffer to a client on the rx path.

Set by devices on the inbound_flags field of an rx descriptor.

Implementations

impl RxFlags

pub const RX_ACCEL_0: RxFlags

Acceleration flag 0.

Acceleration flags are mapped to the acceleration features reported by the [Device] in [Info.rx_accel]. The n-th feature in rx_accel maps to the RX_ACCEL_n RxFlag.

pub const RX_ACCEL_1: RxFlags

pub const RX_ACCEL_2: RxFlags

pub const RX_ACCEL_3: RxFlags

pub const RX_ACCEL_4: RxFlags

pub const RX_ACCEL_5: RxFlags

pub const RX_ACCEL_6: RxFlags

pub const RX_ACCEL_7: RxFlags

pub const RX_ACCEL_8: RxFlags

pub const RX_ACCEL_9: RxFlags

pub const RX_ACCEL_10: RxFlags

pub const RX_ACCEL_11: RxFlags

pub const RX_ACCEL_12: RxFlags

pub const RX_ACCEL_13: RxFlags

pub const RX_ACCEL_14: RxFlags

pub const RX_ACCEL_15: RxFlags

pub const RX_OVERRUN: RxFlags

Device experienced a hardware rx overrun.

Rx overruns are typically set by hardware controllers when a frame event was detected but the frame data couldn’t be captured. Devices should clear the controller flag once this is set on an inbound frame, so future overruns can be detected and reported.

pub const RX_VALIDATION_ERROR: RxFlags

This bit is set if frame validation is performed (such as by hardware acceleration features) and fails.

It’s important to note that some devices may simply discard frames for which validation fails and never notify the client. Rx frames that failed validation are only transmitted to the client if the SessionFlags::REPORT_INVALID_RX option is selected when creating a session.

pub const RX_ECHOED_TX: RxFlags

This is an echoed tx frame, created by a tx request.

Can only be set in sessions that have the LISTEN_TX flag.

impl RxFlags

pub const fn empty() -> RxFlags

Get a flags value with all bits unset.

pub const fn all() -> RxFlags

Get a flags value with all known bits set.

This method will return None if any unknown bits are set.

pub const fn from_bits_truncate(bits: u32) -> RxFlags

pub const fn from_bits_retain(bits: u32) -> RxFlags

Convert from a bits value exactly.

pub fn from_name(name: &str) -> Option<RxFlags>

Get a flags value with the bits of a flag with the given name set.

This method will return None if name is empty or doesn’t correspond to any named flag.

pub const fn is_empty(&self) -> bool

Whether all bits in this flags value are unset.

pub const fn is_all(&self) -> bool

Whether all set bits in a source flags value are also set in a target flags value.

pub fn insert(&mut self, other: RxFlags)

The bitwise or (|) of the bits in two flags values.

pub fn remove(&mut self, other: RxFlags)

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. remove won’t truncate other, but the ! operator will.

pub fn toggle(&mut self, other: RxFlags)

The bitwise exclusive-or (^) of the bits in two flags values.

pub fn set(&mut self, other: RxFlags, value: bool)

Call insert when value is true or remove when value is false.

The bitwise or (|) of the bits in two flags values.

pub const fn difference(self, other: RxFlags) -> RxFlags

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. difference won’t truncate other, but the ! operator will.

pub const fn symmetric_difference(self, other: RxFlags) -> RxFlags

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> RxFlags

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl RxFlags

pub const fn iter(&self) -> Iter<RxFlags>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<RxFlags>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.

impl RxFlags

pub fn has_unknown_bits(&self) -> bool

👎Deprecated: Strict bits should not use has_unknown_bits

pub fn get_unknown_bits(&self) -> u32

👎Deprecated: Strict bits should not use get_unknown_bits
