Struct DatabaseVersion 

pub struct DatabaseVersion { /* private fields */ }

The version of the database a connection talks to, ordered by major, then minor, then patch.

Implementations

impl DatabaseVersion

pub const fn new(major: u32, minor: u32, patch: u32) -> Self

pub const fn major(&self) -> u32

The major version.

pub const fn minor(&self) -> u32

The minor version.

pub const fn patch(&self) -> u32

The patch version.

impl Ord for DatabaseVersion

fn cmp(&self, other: &Self) -> 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.

fn clamp_to<R>(self, range: R) -> Self
