Struct Version 

pub struct Version {
    pub major: u32,
    pub minor: u8,
}

Version are themselves serializable both alone and as part of other Versioned structures. (For obvious recursive reasons, this structure can never be Versioned itself.)

Fields

major: u32

Major version indicates structural layout/encoding changes. Note that this is encoded as a u24.

minor: u8

Minor version indicates forwards compatible changes. e.g. The addition of a layer-file index, bloom filters, file attributes or posix features where reversion to a previous minor will simply lead to loss of these features.

Implementations

impl Version

pub fn deserialize_from<R>(reader: &mut R) -> Result<Self>

where R: Read + ?Sized,

where W: Write,

Trait Implementations

impl Clone for Version

fn clone(&self) -> Version

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Version

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

Formats the value using the given formatter.

impl Default for Version

fn default() -> Version

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Version

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Version

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

Formats the value using the given formatter.

impl PartialEq for Version

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

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TypeFingerprint for Version

fn fingerprint() -> String

impl Copy for Version

impl Eq for Version

impl StructuralPartialEq for Version
