Struct EntityId 

pub struct EntityId(pub u64);

The unique identifier for a CFDP entity, stored as an owned u64.

CFDP Entity IDs are variable-length integers up to 8 bytes. This type normalizes them to a u64 for easy storage, comparison, and hashing.

Tuple Fields

0: u64

Implementations

impl EntityId

pub fn from_bytes(slice: &[u8]) -> Result<Self, CfdpError>

Creates an EntityId from a variable-length byte slice. The slice must be 1 to 8 bytes long.

pub fn write_to_slice(&self, slice: &mut [u8]) -> Result<(), CfdpError>

Serializes this entity ID into a variable-length byte slice.

pub fn len(&self) -> usize

Returns the minimum number of bytes needed to represent this ID.

Trait Implementations

impl Clone for EntityId

fn clone(&self) -> EntityId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EntityId

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

Formats the value using the given formatter.

impl Default for EntityId

fn default() -> EntityId

Returns the “default value” for a type.

impl Hash for EntityId

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 EntityId

fn cmp(&self, other: &EntityId) -> 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 EntityId

fn eq(&self, other: &EntityId) -> 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 EntityId

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