Enum ServerCompatibility 

pub enum ServerCompatibility {
    Supported,
    NewerThanKnown,
    UnknownVersion,
    TooOld {
        minimum: String,
    },
}

The verdict on a server’s version.

Deliberately three states rather than a boolean. “Unrecognised” is not a failure: a server newer than this build resolves forward and works, and refusing it would make every JellyTau release expire the moment the server upgrades. Only a server below the supported floor is refused, where failure is certain rather than merely likely.

TRACES: UR-085 | DR-286

Variants

Supported

A generation this build knows and was tested against.

NewerThanKnown

Parsed, but newer than anything this build knows. Treated as the newest known generation; everything works, and this exists so the UI may mention it rather than so it must.

UnknownVersion

The version string could not be parsed. Treated as supported — we do not refuse a server on the strength of not understanding its version string.

TooOld

Below the supported floor. This one is a refusal.

Fields

minimum: String

Trait Implementations

impl Clone for ServerCompatibility

fn clone(&self) -> ServerCompatibility

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ServerCompatibility

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ServerCompatibility

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl NamedType for ServerCompatibility

fn sid() -> SpectaID

fn named_data_type( type_map: &mut TypeCollection, generics: &[DataType], ) -> NamedDataType

this is equivalent to [Type::inline] but returns a [NamedDataType] instead.

fn definition_named_data_type(type_map: &mut TypeCollection) -> NamedDataType

this is equivalent to [Type::definition] but returns a [NamedDataType] instead.

impl PartialEq for ServerCompatibility

fn eq(&self, other: &ServerCompatibility) -> 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 ServerCompatibility

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Type for ServerCompatibility

fn inline(type_map: &mut TypeCollection, generics: Generics<'_>) -> DataType

Returns the definition of a type using the provided generics.

fn reference(type_map: &mut TypeCollection, generics: &[DataType]) -> Reference

Generates a datatype corresponding to a reference to this type, as determined by its category. Getting a reference to a type implies that it should belong in the type map (since it has to be referenced from somewhere), so the output of definition will be put into the type map.
