Implementations

impl CliErrorRule

pub const fn as_str(self) -> &'static str

pub const fn code(self) -> &'static str

The error.code this failure is reported under.

The classification belongs in the code, beside document_type_mismatch and the rest — not in a second field next to a generic cli_error, which asked an agent to learn a second place to look and cost a closed enum kept in step across four files and four mirrored schemas.
