Enum EntityIdentifier 

pub enum EntityIdentifier {
    Name(String),
    Id(String),
}

An identifier that can be supplied on the command line.

The enum is deliberately small so it can be used as a Clap argument type.
It accepts either

• a plain name (e.g. "bob"), or
• a UUID that is prefixed with an @ (e.g. "@3f4c6b7e-d4d1-4b3f-a7a4-0d5c6b8e1f9b").

The two variants are kept separate so that downstream code can decide whether it should treat the value as a human-readable name or a machine-identifiable UUID.

Variants

Name(String)

A human-readable name.

Id(String)

A UUID that was supplied with a leading @. The @ is stripped when the enum is constructed - only the raw UUID string is stored.

Trait Implementations

impl Clone for EntityIdentifier

fn clone(&self) -> EntityIdentifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EntityIdentifier

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

Formats the value using the given formatter.

impl Display for EntityIdentifier

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

Formats the value using the given formatter.

impl FromStr for EntityIdentifier

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

Parse a string into an EntityIdentifier.

• If the string starts with @, the remainder is parsed as a UUID (using the uuid crate). The @ is not stored.
• Otherwise the string is treated as a name.

type Err = EpochError

The associated error which can be returned from parsing.

impl PartialEq for EntityIdentifier

fn eq(&self, other: &EntityIdentifier) -> 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.
