Struct tor_netdoc::doc::netstatus::RelayFlags

pub struct RelayFlags { /* private fields */ }

A set of recognized directory flags on a single relay.

These flags come from a consensus directory document, and are used to describe what the authorities believe about the relay. If the document contained any flags that we didn’t recognize, they are not listed in this type.

The bit values used to represent the flags have no meaning.

Implementations

impl RelayFlags

pub const AUTHORITY: Self = _

Is this a directory authority?

pub const BAD_EXIT: Self = _

Is this relay marked as a bad exit?

Bad exits can be used as intermediate relays, but not to deliver traffic.

pub const EXIT: Self = _

Is this relay marked as an exit for weighting purposes?

pub const FAST: Self = _

Is this relay considered “fast” above a certain threshold?

pub const GUARD: Self = _

Is this relay suitable for use as a guard relay?

Clients choose their their initial relays from among the set of Guard relays.

pub const HSDIR: Self = _

Does this relay participate on the onion service directory ring?

pub const NO_ED_CONSENSUS: Self = _

If set, there is no consensus for the ed25519 key for this relay.

pub const STABLE: Self = _

Is this relay considered “stable” enough for long-lived circuits?

pub const STALE_DESC: Self = _

Set if the authorities are requesting a fresh descriptor for this relay.

pub const RUNNING: Self = _

Set if this relay is currently running.

This flag can appear in votes, but in consensuses, every relay is assumed to be running.

pub const VALID: Self = _

Set if this relay is considered “valid” – allowed to be on the network.

This flag can appear in votes, but in consensuses, every relay is assumed to be valid.

pub const V2DIR: Self = _

Set if this relay supports a currently recognized version of the directory protocol.

pub const fn empty() -> Self

Returns an empty set of flags.

pub const fn all() -> Self

Returns the set containing all flags.

pub const fn bits(&self) -> u16

Returns the raw value of the flags currently stored.

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

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

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

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const unsafe fn from_bits_unchecked(bits: u16) -> Self

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

Safety

The caller of the bitflags! macro can chose to allow or disallow extra bits for their bitflags type.

The caller of from_bits_unchecked() has to ensure that all bits correspond to a defined flag or that extra bits are valid for this bitflags type.

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: Self) -> bool

Returns true if there are flags common to both self and other.

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

Returns true if all of the flags in other are contained within self.

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

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

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

Toggles the specified flags in-place.

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

Inserts or removes the specified flags depending on the passed value.

pub const fn intersection(self, other: Self) -> Self

Returns the intersection between the flags in self and other.

Specifically, the returned set contains only the flags which are present in both self and other.

This is equivalent to using the & operator (e.g. ops::BitAnd), as in flags & other.

pub const fn union(self, other: Self) -> Self

Returns the union of between the flags in self and other.

Specifically, the returned set contains all flags which are present in either self or other, including any which are present in both (see Self::symmetric_difference if that is undesirable).

This is equivalent to using the | operator (e.g. ops::BitOr), as in flags | other.

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

Returns the difference between the flags in self and other.

Specifically, the returned set contains all flags present in self, except for the ones present in other.

It is also conceptually equivalent to the “bit-clear” operation: flags & !other (and this syntax is also supported).

This is equivalent to using the - operator (e.g. ops::Sub), as in flags - other.

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

Returns the symmetric difference between the flags in self and other.

Specifically, the returned set contains the flags present which are present in self or other, but that are not present in both. Equivalently, it contains the flags present in exactly one of the sets self and other.

This is equivalent to using the ^ operator (e.g. ops::BitXor), as in flags ^ other.

pub const fn complement(self) -> Self

Returns the complement of this set of flags.

Specifically, the returned set contains all the flags which are not set in self, but which are allowed for this type.

Alternatively, it can be thought of as the set difference between Self::all() and self (e.g. Self::all() - self)

This is equivalent to using the ! operator (e.g. ops::Not), as in !flags.
