Enum GpkgVersion 

#[non_exhaustive]
pub enum GpkgVersion {
    V1_0,
    V1_1,
    V1_2,
    V1_3,
    V1_4,
}

GeoPackage specification version, as declared by a file’s pragmas.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

V1_0

GeoPackage 1.0 (application_id “GP10”).

V1_1

GeoPackage 1.1 (application_id “GP11”).

V1_2

GeoPackage 1.2.x (user_version 102xx).

V1_3

GeoPackage 1.3.x (user_version 103xx).

V1_4

GeoPackage 1.4.x (user_version 104xx).

Implementations

impl GpkgVersion

pub fn from_pragmas(application_id: u32, user_version: u32) -> Option<Self>

Classifies a file from its application_id and user_version pragmas.

Returns None if the pragmas do not identify a GeoPackage. user_version values above the newest known 104xx range map to V1_4, because the spec says clients should attempt to read newer minor versions.

Examples

use geopackage_core::GpkgVersion;
use geopackage_core::version::APPLICATION_ID_GPKG;

let version = GpkgVersion::from_pragmas(APPLICATION_ID_GPKG, 10400);
assert_eq!(version, Some(GpkgVersion::V1_4));

pub fn user_version(self) -> Option<u32>

Returns the user_version this crate writes for the given version, or None for 1.0 and 1.1, which predate user_version use.

pub fn as_str(self) -> &'static str

Returns the version as written in the specification, such as "1.4".

The patch level is not included. user_version records it, but the classification drops it: a user_version of 10401 and one of 10400 both classify as Self::V1_4.
