SIFR-PACKAGE-0003: Unsupported Sifr compiler metadata appears in Cargo metadata. - Sifr

SIFR-PACKAGE-0003 belongs to the Package management diagnostic family. It means: unsupported Sifr compiler metadata appears in Cargo metadata.

Why It Happens

Sifr package or workspace metadata violates the package model. Inspect sifr.toml, Cargo metadata, source roots, trust policy, archive contents, package selectors, or projection files as named by the diagnostic.

Use sifr --explain SIFR-PACKAGE-0003 locally to see the renderer’s exact message template and any machine-applicable suggestions for the compiler version you are running.

Erroneous Code

[package]
name = "demo"

How To Fix It

Repair the package manifest, workspace selection, projection files, archive rules, or publish options named by the diagnostic.

Fixed Code

[package]
name = "demo"
version = "0.1.0"

[sifr]
source-root = "src"
