Enum KnownPresent 

#[non_exhaustive]
pub enum KnownPresent {
    Single(String),
    Multiple(Vec<String>),
}

Known-present declaration on a Site.

In JSON this is untagged: a plain string "torvalds" deserialises into KnownPresent::Single, an array ["torvalds", "leomessi"] into KnownPresent::Multiple. Serialisation preserves the form the site was authored with, so single-username entries stay compact.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Single(String)

Exactly one candidate username.

Multiple(Vec<String>)

Two or more candidate usernames. Doctor passes if any resolve to Found.

Implementations

impl KnownPresent

pub fn as_slice(&self) -> &[String]

View all candidate usernames as a slice, in declaration order. Always non-empty for Single; may be empty for a hand-authored Multiple([]) (validation rejects that).

pub fn primary(&self) -> Option<&str>

Primary candidate — the first declared username. Single always has one; Multiple may be empty if a contributor wrote [] (caught by Site::validate).
