Function is_already_published 

pub fn is_already_published(stderr: &str) -> bool

Check whether cargo publish stderr indicates the package version is already present on the registry (a success case for idempotent re-runs).

A version that is already live is not a failure: the artifact the caller asked for is on the registry, so the release has achieved what it came for. Republishing a live version is refused by the registry rather than allowed to overwrite it, which makes a re-run fail on the 24 crates that shipped before the rate limit refused the remaining three. Treating the refusal as success is what lets a re-run converge on the whole workspace instead of stalling on work already done.

Arguments

• &str - cargo publish stderr output

Returns

• bool - True when the output reports the version is already published
