Enum pgdo::version::Version

pub enum Version {
    Pre10(u32, u32, u32),
    Post10(u32, u32),
}

Represents a full PostgreSQL version. This is the kind of thing we see when running pg_ctl --version for example.

The “Current minor” column shown on the PostgreSQL “Versioning Policy” page is what this models.

Variants

Pre10(u32, u32, u32)

Pre-PostgreSQL 10, with major, point, and minor version numbers, e.g. 9.6.17. It is an error to create this variant with a major number >= 10.

Post10(u32, u32)

PostgreSQL 10+, with major and minor version number, e.g. 10.3. It is an error to create this variant with a major number < 10.

Trait Implementations

impl Clone for Version

fn clone(&self) -> Version

Returns a copy 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 Display for Version

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

Formats the value using the given formatter.

impl From<&PartialVersion> for Version

Convert a PartialVersion into a Version that’s useful for comparisons.

The Version returned has 0 (zero) in the place of the missing parts. For example, a partial version of 9.6.* becomes 9.6.0, and 12.* becomes 12.0.

fn from(partial: &PartialVersion) -> Self

Converts to this type from the input type.

impl From<&Version> for PartialVersion

Convert a Version into a PartialVersion.

fn from(version: &Version) -> Self

Converts to this type from the input type.

impl From<PartialVersion> for Version

See From<&PartialVersion> for Version.

fn from(partial: PartialVersion) -> Self

Converts to this type from the input type.

impl From<Version> for PartialVersion

See From<&Version> for PartialVersion.

fn from(version: Version) -> Self

Converts to this type from the input type.

impl FromStr for Version

type Err = VersionError

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 Version

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 Version

fn cmp(&self, other: &Version) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Version

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

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.
