Failed to merge inline config: {err}

Error message

Failed to merge inline config: {err}

What it means

Raised in load_dioxus_config when the inline dioxus config embedded in the source file (via extract_inline_config_from_) fails to deserialize; {err} carries the TOML/deser detail. The faulting input is the inline `dioxus::Config` block in the Rust source, not Dioxus.toml.
