Struct VersionPin 

pub struct VersionPin;

A zero-sized type enforcing serde to serialize/deserialize it to a constant number representing version of Metadata schema.

The version number corresponds to the major version of this crate.

Implementations

impl VersionPin

pub const fn numeric(self) -> u64

Get version as a number.

pub const fn from_numeric(num: u64) -> Option<Self>

Construct this pin if num equals to the pinned version.

Trait Implementations

impl Clone for VersionPin

fn clone(&self) -> VersionPin

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VersionPin

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

Formats the value using the given formatter.

impl Default for VersionPin

fn default() -> VersionPin

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for VersionPin

fn deserialize<D: Deserializer<'de>>(d: D) -> Result<VersionPin, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for VersionPin

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

Formats the value using the given formatter.

impl From<VersionPin> for u64

fn from(pin: VersionPin) -> Self

Converts to this type from the input type.

impl Hash for VersionPin

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 VersionPin

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

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

fn partial_cmp(&self, other: &VersionPin) -> 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 VersionPin

fn serialize<S: Serializer>(&self, s: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl Copy for VersionPin

impl Eq for VersionPin
