Enum EpochIdentifier 

pub enum EpochIdentifier {
    Tag(String),
    Id(EpochId),
}

A flexible identifier for any epoch - the world may be addressed by a numeric ID or by a friendly tag (e.g. "winter-b").

The enum is untagged so that serialising/deserialising does not add a wrapper field, e.g. {"Tag":"foo"}.
Instead the JSON representation is exactly the inner value:

• "42" → EpochIdentifier::Id(EpochId::new(42))
• "foo" → EpochIdentifier::Tag("foo".into())

Variants

Tag(String)

A textual tag that maps to a numeric epoch ID in EpochConfig::tags.

Id(EpochId)

The raw numeric identifier of the epoch.

Trait Implementations

impl Clone for EpochIdentifier

fn clone(&self) -> EpochIdentifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EpochIdentifier

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EpochIdentifier

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromStr for EpochIdentifier

fn from_str(s: &str) -> Result<Self, Self::Err>

Try to parse either a decimal number (-> Id) or any non-empty string (-> Tag).

Errors are converted to a Clap error so that the CLI shows a nice message.

type Err = Error

The associated error which can be returned from parsing.

impl Hash for EpochIdentifier

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 PartialEq for EpochIdentifier

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
