Failed to parse Dioxus.toml at {path:?}: {err}
Error message
Failed to parse Dioxus.toml at {path:?}: {err} What it means
Raised in load_dioxus_config when toml::from_str fails on the contents of the discovered Dioxus.toml at the given path. The file exists but is syntactically invalid TOML or has fields that do not deserialize into DioxusConfig; the underlying toml error with position is embedded as {err}.
