Crate surface What does rtb_error::* export? What is the MSRV? Which Cargo features exist?
Error and Result What are the variants, their diagnostic codes, their help text, and what converts into them?
hook module What do the three install_* functions do, in what order must they be called, and what changes about rendering?

The generated API documentation — every signature, every trait implementation — is on docs.rs/rtb-error. These pages cover the things a signature does not tell you: defaults, ordering requirements, and what goes wrong.
