pub struct Field {

    pub description: &'static str,
    pub options: &'static [(&'static str, &'static str)],
    pub doc_link: &'static str,
}

Constants live next to the call sites (e.g. init/container.rs) and are passed by reference into PromptSource methods.

Fields

User-facing question, e.g. "Pick a provider style".

description: &'static str

Long-form explanation shown when the user types ?.

options: &'static [(&'static str, &'static str)]

Discrete choices as (value, blurb) pairs. Empty for free-text fields.

doc_link: &'static str

Path under the repo root, e.g. "doc/concepts/llm-providers.md". Help output renders this as a public documentation URL.
