Struct Chain 

pub struct Chain {
    pub repo: String,
    pub from: String,
    pub target: Option<String>,
    pub line: LinkState,
    pub signature: LinkState,
    pub push: LinkState,
    pub log: LinkState,
    pub build: Option<LinkState>,
    pub build_log: Option<LinkState>,
}

The chain, as far as it could be walked.

Fields

repo: String

<namespace>/<repo>.

from: String

The revision the walk started from.

target: Option<String>

path:line, one-based, as the operator wrote it.

line: LinkState

Link 1: which commit put the line there.

signature: LinkState

Link 2: the commit’s own signature.

push: LinkState

Link 3: the push that landed the commit.

log: LinkState

Link 4: that push’s place in the transparency log.

build: Option<LinkState>

Links 5–6: the build that produced the artifact, and its signature.

None when no artifact was named — the chain was walked from a line of source and the build half was never asked about. Distinct from a link that was asked about and could not be proven.

build_log: Option<LinkState>

Link 7: the build record’s place in the build log.

Implementations

impl Chain

pub fn links(&self) -> Vec<(&'static str, &'static str, &LinkState)>

Every link, in chain order, with a stable id and a print label.

The ONE enumeration (one implementation): std::fmt::Display prints the labels, Chain::to_proto ships the ids, and both walk this list — so a link added here reaches the CLI and Admin.VerifyChain together, and cannot reach one without the other.

pub fn to_proto(&self) -> VerifyChainResponse

The chain rendered for Admin.VerifyChain — a projection of Chain::links, never a second verdict.

pub fn is_unbroken(&self) -> bool

Unbroken means every link is proven. A single Unproven is not unbroken: an unverified link is a hole in the chain, and calling it green is exactly the false confidence the roadmap’s Risker section names.

pub fn is_broken(&self) -> bool

true if anything was actively wrong, as opposed to merely unchecked.
