Struct ImageRef 

pub struct ImageRef {
    pub app: String,
    pub tag: Option<String>,
    pub digest: Option<String>,
}

What a compose file’s registry: image names: an app’s repository in the org, and a tag and/or a digest.

Fields

app: String

tag: Option<String>

digest: Option<String>

Implementations

impl ImageRef

pub fn parse(s: &str) -> Result<ImageRef>

APP[:TAG][@sha256:...], what follows registry:.

pub fn tag_or_latest(&self) -> &str

The tag, latest by default.

pub fn render(&self) -> String

APP:TAG@DIGEST, as written after registry:.

pub fn pinned(&self, digest: &str) -> ImageRef

This reference pinned to digest (the tag is kept for people).

pub fn pull_alias(&self, org: &OrgId) -> String

The incus alias to pull: <org>/<app>@digest, or :tag. Skopeo refuses a tag and a digest together, and the digest is what counts.
