Struct Surrogate 

pub struct Surrogate(pub u32);

Global surrogate identifier.

A u32 newtype carrying the same comparison + hashing semantics as the underlying integer. The Display impl renders as sur:N for diagnostics (mirrors the Lsn convention).

Tuple Fields

0: u32

Implementations

impl Surrogate

pub const ZERO: Surrogate

The zero surrogate. Reserved as a sentinel — real allocation starts at 1.

pub const fn new(value: u32) -> Surrogate

Construct a surrogate from a raw u32.

pub const fn as_u32(self) -> u32

Raw u32 value.

Trait Implementations

impl Clone for Surrogate

fn clone(&self) -> Surrogate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Surrogate

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Surrogate

fn deserialize<__D>( __deserializer: __D, ) -> Result<Surrogate, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Surrogate

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

Formats the value using the given formatter.

impl<'__msgpack_de> FromMessagePack<'__msgpack_de> for Surrogate

fn read<R>(reader: &mut R) -> Result<Surrogate, Error>

where R: Read<'__msgpack_de>, Surrogate: Sized,

Reads the MessagePack representation of this value from the provided reader.

impl Hash for Surrogate

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 Surrogate

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

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

fn partial_cmp(&self, other: &Surrogate) -> 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 Serialize for Surrogate

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToMessagePack for Surrogate

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

where W: Write,

Writes the MessagePack representation of this value into the provided writer.

impl Copy for Surrogate

impl Eq for Surrogate
