Struct SchemaVersion 

pub struct SchemaVersion {
    pub major: u16,
    pub minor: u16,
}

Semantic version for schemas.

Uses major.minor versioning:

• Major version changes indicate breaking changes
• Minor version changes indicate backward-compatible changes

Example

let v1 = SchemaVersion::new(1, 0);
let v1_1 = SchemaVersion::new(1, 1);
let v2 = SchemaVersion::new(2, 0);

assert!(v1.is_compatible_with(&v1_1)); // Same major = compatible
assert!(!v1.is_compatible_with(&v2));  // Different major = breaking

Fields

major: u16

Major version (breaking changes).

minor: u16

Minor version (backward-compatible changes).

Implementations

impl SchemaVersion

pub const fn new(major: u16, minor: u16) -> Self

Create a new schema version.

pub fn parse(s: &str) -> Option<Self>

Parse a version string (e.g., “v1”, “v1.2”, “1.0”).

Supports formats:

• “v1” → (1, 0)
• “v1.2” → (1, 2)
• “1.0” → (1, 0)
• “1” → (1, 0)

pub fn is_compatible_with(&self, other: &Self) -> bool

Check if this version is compatible with another version.

Two versions are compatible if they have the same major version, and this version’s minor is >= the other’s minor.

pub fn is_successor_of(&self, other: &Self) -> bool

Check if this version is a direct successor to another.

pub fn next_minor(&self) -> Self

Get the next minor version.

pub fn next_major(&self) -> Self

Get the next major version.

pub fn to_version_string(&self) -> String

Format as a version string (e.g., “v1.0”).

pub fn to_short_string(&self) -> String

Format as a short version string (e.g., “v1” if minor is 0).

Trait Implementations

impl Clone for SchemaVersion

fn clone(&self) -> SchemaVersion

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SchemaVersion

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

Formats the value using the given formatter.

impl Default for SchemaVersion

fn default() -> Self

Returns the “default value” for a type.

impl Display for SchemaVersion

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

Formats the value using the given formatter.

impl FromStr for SchemaVersion

type Err = &'static str

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 SchemaVersion

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 SchemaVersion

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.

impl PartialEq for SchemaVersion

fn eq(&self, other: &SchemaVersion) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for SchemaVersion

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
