Enum PromptSelector 

pub enum PromptSelector {
    Latest,
    Label(String),
    Version(PromptVersion),
}

Which version of a prompt is wanted.

The three arms are three different postures towards a moving registry, and they are worth choosing between deliberately:

• Latest takes whatever the source considers current. Fine for a compiled-in source, where “current” means “what is in this binary”.
• Label takes the version somebody has marked — production being the usual one. Convenient, and it means an edit in the registry changes a running system without a deploy, which is the trade being made.
• Version pins. A registry edit then cannot change what the system does; only a deploy can, and the pinned version is what the replay record cites. This is the arm a deployment that cares about reproducibility uses.

Deliberately not #[non_exhaustive], unlike most growable enums in this crate. A PromptSource has to decide what every selector means for it, and a wildcard arm decides by accident: it would serve something for a selector the source has never heard of, which is the one behaviour a pin exists to rule out. Adding an arm here should break every source and make each of them say what it does.

Variants

Latest

Whatever the source considers current.

Label(String)

The version carrying this deployment label.

Version(PromptVersion)

This exact version, and no other.

Implementations

impl PromptSelector

pub fn label(label: impl Into<String>) -> Self

A label selector.

pub fn version(version: impl Into<PromptVersion>) -> Self

A pinned-version selector.

pub fn as_key(&self) -> String

A short stable rendering, used as part of a cache key and safe to log.

pub const fn is_pinned(&self) -> bool

Returns true when this selector names one immutable version, so what comes back cannot change under a running system.

Trait Implementations

impl Clone for PromptSelector

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PromptSelector

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

Formats the value using the given formatter.

impl Default for PromptSelector

fn default() -> Self

Returns the “default value” for a type.

impl Display for PromptSelector

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

impl Eq for PromptSelector

impl Hash for PromptSelector

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,

impl Ord for PromptSelector

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for PromptSelector

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

impl PartialOrd for PromptSelector

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.
