Enum Mode 

pub enum Mode {
    Auto,
    Explicit,
    UnixTimestamp,
    Legacy,
    Scientific,
}

Only relevant for purely numeric dates.

Variants

Auto

Default mode — Smart heuristic:

• 5/7-digit pure-numeric inside LEGACY_ORDINAL_YEAR_RANGE → treated as business ordinal (YYYYDDD / YYDDD)
• Outside that range or invalid ordinal → treated as MJD or JD

Explicit

When combined with a provided Vec of formats in parse no other formats are tried.

UnixTimestamp

It’s some sort of unix timestamp

Legacy

Business/legacy-only mode: Only accepts ordinal dates (YYYYDDD / YYDDD). No astronomy (JD/MJD) support. Strict and predictable for ERP/mainframe data.

Scientific

Scientific / astronomy-first mode: Prioritizes MJD (5-digit) and JD (7-digit). Ordinals are only fallback. Use this when parsing data from astronomy tools or large numeric epochs.

Trait Implementations

impl Clone for Mode

fn clone(&self) -> Mode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mode

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

Formats the value using the given formatter.

impl Default for Mode

fn default() -> Mode

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Mode

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Mode

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Tsify for Mode

const DECL: &'static str = "/**\n * Only relevant for purely numeric dates.\n */\nexport type Mode = \"Auto\" | \"Explicit\" | \"UnixTimestamp\" | \"Legacy\" | \"Scientific\";"

const SERIALIZATION_CONFIG: SerializationConfig

type JsType = JsType

fn into_js(&self) -> Result<Self::JsType, Error>

where Self: Serialize,

fn from_js<T>(js: T) -> Result<Self, Error>

where T: Into<JsValue>, Self: DeserializeOwned,
