[−][src]Struct abi_stable::version::VersionNumber
The parsed (<major>.<minor>.<patch>
) version number of a library.
Post 1.0 major version
Major versions are mutually incompatible for both users and implementors.
Minor allow users to have a version less than or equal to that of the implementor, and disallows implementors from making changes that would break any previous minor release (with the same major number).
Patch cannot change the api/abi of the library at all,fixes only.
Fields
major: u32
minor: u32
patch: u32
Methods
impl VersionNumber
[src]
pub fn new(vn: VersionStrings) -> Result<Self, ParseVersionError>
[src]
pub fn is_compatible(self, library_implementor: VersionNumber) -> bool
[src]
Whether the self
version number is compatible with the
library_implementor version number.
This uses the same semver rules as cargo:
-
For 0.y.z ,y is interpreted as a major version, z is interpreted as the minor version,
-
For x.y.z ,x>=1,y is interpreted as a minor version.
-
Libraries are compatible so long as they are the same major version with a minor_version >=
self
.
