Struct SessionFlags

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

Additional session options.

Implementations

impl SessionFlags

pub const PRIMARY: SessionFlags

Attach as primary session.

Sessions marked with the PRIMARY bit get the following different treatment:

• If no PRIMARY sessions are attached, the device will not serve rx frames to non-PRIMARY sessions.
• If there’s only one PRIMARY session active, it may get a zero-copy data path from the the backing hardware, if the underlying implementation supports it.

pub const LISTEN_TX: SessionFlags

Listen for outgoing frames.

LISTEN_TX sessions receive any outgoing frames (from all sessions) on its rx path. Can be used for snooping traffic. Sessions marked with LISTEN_TX may also send frames, but they should keep in mind that they’ll ALWAYS receive those frames back on their rx path (no origin session filtering is performed).

pub const REPORT_INVALID_RX: SessionFlags

Receive invalid rx frames.

Sessions marked with REPORT_INVALID_RX are interested in receiving frames that were rejected by internal device checks or payload validation performed by hardware. Due to the nature of some hardware platforms, sessions marked with REPORT_INVALID_RX may still not receive frames that fail validation if the hardware implementation simply drops the frame and doesn’t expose it to the software stack. Sessions NOT marked with REPORT_INVALID_RX, in contrast, will NEVER receive an rx frame with the RX_VALIDATION_ERROR flag set.

pub const RECEIVE_RX_POWER_LEASES: SessionFlags

Receive rx power leases.

Sessions marked with RECEIVE_RX_POWER_LEASES receive [DelegatedRxLease]s through [Session.WatchDelegatedRxLease] calls.

pub const fn empty() -> SessionFlags

Get a flags value with all bits unset.

pub const fn all() -> SessionFlags

Get a flags value with all known bits set.

pub const fn bits(&self) -> u16

Get the underlying bits value.

The returned value is exactly the bits set in this flags value.

pub const fn from_bits(bits: u16) -> Option<SessionFlags>

Convert from a bits value.

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

pub const fn from_bits_truncate(bits: u16) -> SessionFlags

Convert from a bits value, unsetting any unknown bits.

pub const fn from_bits_retain(bits: u16) -> SessionFlags

Convert from a bits value exactly.

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

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 known bits in this flags value are set.

pub const fn contains(&self, other: SessionFlags) -> bool

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

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

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

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

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: SessionFlags)

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

pub fn set(&mut self, other: SessionFlags, 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: SessionFlags) -> SessionFlags

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: SessionFlags) -> SessionFlags

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

pub const fn complement(self) -> SessionFlags

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

impl SessionFlags

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

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<SessionFlags>

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 SessionFlags

pub fn has_unknown_bits(&self) -> bool

👎Deprecated: Strict bits should not use has_unknown_bits

pub fn get_unknown_bits(&self) -> u16

👎Deprecated: Strict bits should not use get_unknown_bits
