Struct ImageRef 

pub struct ImageRef {
    pub registry: String,
    pub repository: String,
    pub tag: String,
    pub digest: String,
}

Container image reference identifying a specific image to pull.

Digest is required. Every executable image reference in the workspace is content-addressed by sha256:<hex>. The tag is preserved as a human-readable identifier but is not the source of truth — registries return mutable tag → digest mappings and we don’t trust them for reproducibility. R438-T3 tightened digest: Option<String> → String to make unpinned-image bugs impossible by construction.

Two deserialize shapes. The struct form (registry/repository/tag/digest fields) is the on-disk envelope. A string form (image = "ghcr.io/foo/bar:v1@sha256:<hex>") is also accepted and is the shape W164 transform recipes (R438-T4) and W165 BuildMode::InContainer (R438-T6) use. Both shapes go through a single parser ([compose_import::parse_pinned_image_ref]) that rejects bare-tag references at serde-deserialize.

Fields

registry: String

Registry hostname, e.g. "ghcr.io" or "localhost:5000".

repository: String

Repository path, e.g. "noisetable/api".

tag: String

Tag, e.g. "v1.4.2" or "latest". Informational — the digest is the source of truth for image identity.

digest: String

Content-addressed pinned identity, e.g. "sha256:abc...". Required.

Implementations

impl ImageRef

pub const UNPINNED_DIGEST: &'static str = "sha256:0000000000000000000000000000000000000000000000000000000000000000"

The all-zeros sha256 digest that marks an image reference as not content-pinned. No real image can carry it, so a build that never injected a compile-time digest (dev builds) or a catalog image that isn’t published-and-pinned yet lands on this sentinel. This is the single source of truth both the catalog emitter (task::default_image::catalog_image, which writes it) and the container-runtime resolvers (Self::pull_ref, via kamaji) agree on — keeping them here means they cannot drift. [testing::TEST_DIGEST] is the same value re-exported for fixtures.

pub fn parse_pinned(s: &str) -> Result<Self, String>

Parse a full digest-pinned image reference — [registry/]repo[:tag]@sha256:<hex> — into its parts.

This is the public door onto the same parser the ImageRef string-form Deserialize arm uses, so a config that spells an image as one string (a qed step.image, a transform recipe) and a config that spells it as a struct land on identical semantics. A bare tag is rejected: the whole point of the string form is that it carries the digest.

pub fn docker_ref(&self) -> String

Format this reference as a Docker-compatible image string, {registry}/{repository}:{tag}@{digest}. Tag is included for human readability; the digest is what the pull resolves against. Always emits the digest — this is the display/logging form; use Self::pull_ref for the string handed to a container runtime.

pub fn is_pinned(&self) -> bool

True when this reference carries a real content-addressed digest, i.e. its digest is not the all-zeros Self::UNPINNED_DIGEST sentinel.

pub fn pull_ref(&self) -> String

The reference string to hand a container runtime for pull/resolve.

• Pinned (real digest): {registry}/{repository}:{tag}@{digest} — content-addressed, the reproducible path.
• Unpinned (all-zeros Self::UNPINNED_DIGEST): {registry}/{repository}:{tag} — tag-only. No registry or local store holds an image under the sentinel digest, so …@sha256:0000… can never resolve; a tag-pulled or locally-built image is keyed by registry/repo:tag. This is the tag-fallback path that lets a not-yet-published catalog image (e.g. a from-source build-worker image) still pull by tag.

impl StructuralPartialEq for ImageRef

impl TS for ImageRef

type WithoutGenerics = ImageRef

If this type does not have generic parameters, then WithoutGenerics should just be Self. If the type does have generic parameters, then all generic parameters must be replaced with a dummy type, e.g ts_rs::Dummy or ().
The only requirement for these dummy types is that EXPORT_TO must be None.

type OptionInnerType = ImageRef

If the implementing type is std::option::Option<T>, then this associated type is set to T. All other implementations of TS should set this type to Self instead.

fn ident(cfg: &Config) -> String

Identifier of this type, excluding generic parameters.

fn docs() -> Option<String>

JSDoc comment to describe this type in TypeScript - when TS is derived, docs are automatically read from your doc comments or #[doc = ".."] attributes

fn name(cfg: &Config) -> String

Name of this type in TypeScript, including generic parameters

fn decl_concrete(cfg: &Config) -> String

Declaration of this type using the supplied generic arguments. The resulting TypeScript definition will not be generic. For that, see TS::decl(). If this type is not generic, then this function is equivalent to TS::decl().

fn decl(cfg: &Config) -> String

Declaration of this type, e.g. type User = { user_id: number, ... }. This function will panic if the type has no declaration.

fn inline(cfg: &Config) -> String

Formats this types definition in TypeScript, e.g { user_id: number }. This function will panic if the type cannot be inlined.

fn inline_flattened(cfg: &Config) -> String

Flatten a type declaration. This function will panic if the type cannot be flattened.

fn visit_generics(v: &mut impl TypeVisitor)

where Self: 'static,

Iterates over all type parameters of this type.

fn output_path() -> Option<PathBuf>

Returns the output path to where T should be exported, relative to the output directory. The returned path does not include any base directory.

fn visit_dependencies(v: &mut impl TypeVisitor)

where Self: 'static,

Iterates over all dependency of this type.

fn dependencies(cfg: &Config) -> Vec<Dependency>

where Self: 'static,

Resolves all dependencies of this type recursively.

fn export(cfg: &Config) -> Result<(), ExportError>

where Self: 'static,

Manually export this type to the filesystem. To export this type together with all of its dependencies, use TS::export_all.

fn export_all(cfg: &Config) -> Result<(), ExportError>

where Self: 'static,

Manually export this type to the filesystem, together with all of its dependencies. To export only this type, without its dependencies, use TS::export.

fn export_to_string(cfg: &Config) -> Result<String, ExportError>

where Self: 'static,

Manually generate bindings for this type, returning a String. This function does not format the output, even if the format feature is enabled.
