Struct ExtensionRef 

pub struct ExtensionRef { /* private fields */ }

Reference to an env extension binding: ext://<descriptor-path>[/<instance>].

Unlike SecretRef / RuntimeRef, an extension ref carries no env segment — extensions are resolved within the already-known env context of the workload that names them. <descriptor-path> is a PackDescriptor path (version-independent — the binding owns the concrete version); the optional <instance> selects one of N instances of the same extension type. Lookup is by (path, instance_id) against Environment::extensions, the same key its uniqueness invariant enforces.

Implementations

impl ExtensionRef

pub fn try_new(raw: impl Into<String>) -> Result<Self, ExtensionRefParseError>

pub fn as_str(&self) -> &str

pub fn path(&self) -> &str

Version-independent descriptor path the ref selects.

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

Instance selector, or None for the default (unnamed) instance.

Trait Implementations

impl Clone for ExtensionRef

fn clone(&self) -> ExtensionRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExtensionRef

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ExtensionRef

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ExtensionRef

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

Formats the value using the given formatter.

impl Eq for ExtensionRef

impl From<ExtensionRef> for String

fn from(value: ExtensionRef) -> Self

Converts to this type from the input type.

impl FromStr for ExtensionRef

type Err = ExtensionRefParseError

The associated error which can be returned from parsing.

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

Parses a string s to return a value of this type.

impl Hash for ExtensionRef

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 ExtensionRef

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for ExtensionRef

impl TryFrom<String> for ExtensionRef

type Error = ExtensionRefParseError

The type returned in the event of a conversion error.

fn try_from(value: String) -> Result<Self, Self::Error>

Performs the conversion.
