pub struct Version {
    pub major: u64,
    pub minor: Option<u64>,
    pub release: Option<u64>,
}
Expand description

PostgreSQL version struct. The version is a simple wrapper around a string. Actively supported major versions of PostgreSQL are defined as constants. The oldest supported version is will be marked as deprecated. Deprecated versions will be removed in a future release following semver conventions for this crate.

Implementations§

source§

impl Version

source

pub const fn new(major: u64, minor: Option<u64>, release: Option<u64>) -> Self

source

pub fn matches(&self, version: &Version) -> bool

Matches the version against another version. Provides a simple way to match against a major, major/minor, or major/minor/release version. Returns true if the major version matches and the minor version matches or is not specified. Returns true if the major and minor versions match and the release matches or is not specified. Returns false otherwise.

§Examples

The methods of this trait must be consistent with each other and with those of PartialEq. The following conditions must hold:

  1. 16 matches 16.1.0, 16.1.1, 16.2.0, etc.
  2. 16.1 matches 16.1.0, 16.1.1, etc.
  3. 16.1.0 matches only 16.1.0
  4. 15 does not match 16.1.0
  5. 16.0 does not match 16.1.0
  6. 16.1.0 does not match 16.1.1
