Struct ExternalReference 

pub struct ExternalReference {
    pub node: Atom,
    pub creation: u32,
    pub ids: Vec<u32>,
    pub local_ext_bytes: Option<Bytes>,
}

Represents an Erlang reference originating from a remote node.

Like PIDs, references can be encoded via LOCAL_EXT. The local_ext_bytes field preserves the original encoding for transparent re-encoding.

Note: The local_ext_bytes field is excluded from equality, hash, and ordering comparisons.

Fields

node: Atom

creation: u32

ids: Vec<u32>

local_ext_bytes: Option<Bytes>

If this reference was decoded from LOCAL_EXT, this contains the hash (8 bytes) and nested term bytes for transparent re-encoding.

Bytes offer zero-copy cloning.

Implementations

impl ExternalReference

pub fn new(node: Atom, creation: u32, ids: Vec<u32>) -> Self

pub fn with_local_ext_bytes( node: Atom, creation: u32, ids: Vec<u32>, local_ext_bytes: impl Into<Bytes>, ) -> Self

Creates a new reference with preserved LOCAL_EXT bytes.

Accepts any type that can be converted to Bytes (e.g., Vec<u8>, &[u8], Bytes).

pub fn is_local_ext(&self) -> bool

Returns true if this reference was decoded from LOCAL_EXT encoding.

Trait Implementations

impl Clone for ExternalReference

fn clone(&self) -> ExternalReference

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExternalReference

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

Formats the value using the given formatter.

impl Hash for ExternalReference

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 ExternalReference

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 ExternalReference

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 ExternalReference

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

Tests less than or equal to (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.
