Function seed

core/src/workspace/mod.rs:1086–1092

Seed a file into the mock and return its current version, so callers can use it as an expected value without hardcoding the version scheme.

(fs: &Arc<InMemoryFileSystem>, path: &str, content: &str)

    /// can use it as an expected value without hardcoding the version
    /// scheme.
    async fn seed(fs: &Arc<InMemoryFileSystem>, path: &str, content: &str) -> String {
        use super::WorkspaceFileSystemExt;
        let ws_path = WorkspacePath::from_normalized(path);
        (*fs).write_text(&ws_path, content).await.unwrap();
        let (_, version) = (*fs).read_text_with_version(&ws_path).await.unwrap();
        version
    }
