Struct ProcId 

pub struct ProcId { /* private fields */ }

Identifies a process in the actor system.

Identity (Eq, Hash, Ord) is determined by uid.

Implementations

impl ProcId

pub fn new(uid: Uid, label: Option<Label>) -> Self

Create a new ProcId.

pub fn anonymous() -> Self

Create an anonymous instance ProcId with a random uid.

pub fn singleton(label: Label) -> Self

Create a singleton ProcId identified by the given label.

pub fn instance(label: Label) -> Self

Create an instance ProcId with a random uid and the given label.

pub fn uid(&self) -> &Uid

Returns the uid.

pub fn label(&self) -> Option<&Label>

Returns the label.

pub fn to_path_elem(&self, base_dir: &Path) -> PathBuf

Returns a unique path for this proc in the given directory. This is stable over the lifetime of the ProcId.

The basename is proc_id.pseudo_uid() rendered in base58, which keeps the path short and host-unique. Both ends of a local link compute the same pseudo uid, so the path is consistent without coordination. The returned PathBuf is the on-disk socket path, which callers may use to pre-flight existence before dialing.

pub fn pseudo_uid(&self) -> Uid

A Uid suitable as a short, host-unique identifier — for example, as a basename in a filesystem path.

For an instance proc, this is the proc’s actual uid. For a singleton, it is Uid::Instance(hash(label)), a stable value derived from the singleton’s name. Singletons are host-unique by name, so this remains host-unique. We call it “pseudo” because in the singleton case it does not match the proc’s true uid.

Trait Implementations

impl Clone for ProcId

fn clone(&self) -> ProcId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProcId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ProcId

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ProcId

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

Formats the value using the given formatter.

impl FromStr for ProcId

type Err = IdParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for ProcId

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 ProcId

fn cmp(&self, other: &Self) -> 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 ProcId

fn eq(&self, other: &Self) -> 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 ProcId

fn partial_cmp(&self, other: &Self) -> 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 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.

impl Serialize for ProcId

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
