Struct SchemaVersion 

pub struct SchemaVersion(/* private fields */);

Newtype wrapping the schema-version literal.

Parses only the exact string "1". Any other value yields PackParseError::InvalidSchemaVersion so consumers can emit an actionable “upgrade grex” or “downgrade pack” message.

Implementations

impl SchemaVersion

pub fn current() -> Self

The single supported schema version literal.

pub fn as_str(&self) -> &str

Borrow the wrapped literal.

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<'de> Deserialize<'de> for SchemaVersion

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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 Serialize for SchemaVersion

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
