Struct HostID

pub struct HostID {
    pub id: [u8; 16],
}

A one_two_eight identifier.

Fields

id: [u8; 16]

The raw bytes for this identifier.

Implementations

impl HostID

pub const BOTTOM: HostID

pub fn generate() -> Option<HostID>

Generate a new identifier, failing if urandom fails.

pub fn from_human_readable(s: &str) -> Option<Self>

Construct an identifier from its human-readable form.

pub fn human_readable(&self) -> String

Construct a string corresponding to the human-readable form of this identifier.

pub fn prefix_free_readable(&self) -> String

Return the prefix-free encoding of this identifier.

pub fn new(id: [u8; 16]) -> Self

pub fn next(self) -> Self

Increment the identifier by one.

Trait Implementations

impl Clone for HostID

fn clone(&self) -> HostID

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HostID

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

Formats the value using the given formatter.

impl Default for HostID

fn default() -> HostID

Returns the “default value” for a type.

impl Display for HostID

impl<'a> FieldPackHelper<'a, message<HostID>> for HostID

fn field_pack_sz(&self, tag: &Tag) -> usize

The size of encoding self with tag.

fn field_pack(&self, tag: &Tag, out: &mut [u8])

Pack the tag into the output buffer.

impl<'a> FieldUnpackHelper<'a, message<HostID>> for HostID

fn merge_field(&mut self, proto: message<HostID>)

Merge the proto into self.

impl From<message<HostID>> for HostID

fn from(proto: message<HostID>) -> Self

Converts to this type from the input type.

impl FromStr for HostID

type Err = &'static str

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 HostID

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 HostID

fn cmp(&self, other: &HostID) -> 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 Packable for HostID

fn pack_sz(&self) -> usize

pack_sz returns the number of bytes required to serialize the Packable object.

fn pack(&self, buf: &mut [u8])

pack fills in the buffer out with the packed binary representation of the Packable object. The implementor is responsible to ensure that out is exactly pack_sz() bytes and implementations are encouraged to assert this.

fn stream<W>(&self, writer: &mut W) -> Result<usize, Error>

where W: Write, Self: Sized, &'a Self: for<'a> Packable,

stream writes the object to the provided writer using the same representation that would be used in a call to pack. The implementor is responsible for making sure that the number of bytes written is exactly equal to the number of required bytes.

impl PartialEq for HostID

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

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

impl<'a> Unpackable<'a> for HostID

type Error = Error

Type of error this unpackable returns.

fn unpack<'b: 'a>(buf: &'b [u8]) -> Result<(Self, &'b [u8]), Error>

unpack attempts to return an Unpackable object stored in a prefix of buf. The method returns the result and remaining unused buffer.
