Struct casper_types::ProtocolVersion

pub struct ProtocolVersion(/* private fields */);

A newtype wrapping a SemVer which represents a Casper Platform protocol version.

Implementations

impl ProtocolVersion

pub const V1_0_0: ProtocolVersion = _

Version 1.0.0.

pub const fn new(version: SemVer) -> ProtocolVersion

Constructs a new ProtocolVersion from version.

pub const fn from_parts(major: u32, minor: u32, patch: u32) -> ProtocolVersion

Constructs a new ProtocolVersion from the given semver parts.

pub fn value(&self) -> SemVer

Returns the inner SemVer.

pub fn check_next_version(&self, next: &ProtocolVersion) -> VersionCheckResult

Checks if next version can be followed.

pub fn is_compatible_with(&self, version: &ProtocolVersion) -> bool

Checks if given protocol version is compatible with current one.

Two protocol versions with different major version are considered to be incompatible.

Trait Implementations

impl Clone for ProtocolVersion

fn clone(&self) -> ProtocolVersion

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ProtocolVersion

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

Formats the value using the given formatter.

impl Default for ProtocolVersion

fn default() -> ProtocolVersion

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ProtocolVersion

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for ProtocolVersion

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

Formats the value using the given formatter.

impl FromBytes for ProtocolVersion

fn from_bytes(bytes: &[u8]) -> Result<(Self, &[u8]), Error>

Deserializes the slice into Self.

fn from_vec(bytes: Vec<u8>) -> Result<(Self, Vec<u8>), Error>

Deserializes the Vec<u8> into Self.

impl FromStr for ProtocolVersion

type Err = ParseSemVerError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, ParseSemVerError>

Parses a string s to return a value of this type.

impl Hash for ProtocolVersion

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 ProtocolVersion

fn cmp(&self, other: &ProtocolVersion) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ProtocolVersion

fn eq(&self, other: &ProtocolVersion) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for ProtocolVersion

fn partial_cmp(&self, other: &ProtocolVersion) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for ProtocolVersion

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

Serialize this value into the given Serde serializer.

impl ToBytes for ProtocolVersion

fn to_bytes(&self) -> Result<Vec<u8>, Error>

Serializes &self to a Vec<u8>.

fn serialized_length(&self) -> usize

Returns the length of the Vec<u8> which would be returned from a successful call to to_bytes() or into_bytes(). The data is not actually serialized, so this call is relatively cheap.

fn write_bytes(&self, writer: &mut Vec<u8>) -> Result<(), Error>

Writes &self into a mutable writer.

fn into_bytes(self) -> Result<Vec<u8>, Error>where Self: Sized,

Consumes self and serializes to a Vec<u8>.
