ineed 0.1.1

//! This example shows how you can customize the format of a whole chaining prompt.
//!
//! The accepted format rules for the chain is the intersection of the accepted format rules
//! of every prompt it contains. For example, if we're prompting the chain C = A + B, and the prompt
//! A accepts the rules [msg_prefix, input_prefix], and B accepts the rules [msg_prefix, repeat_prompt],
//! C will accept the rules \[msg_prefix].
//!
//! You can still customize each prompt more specifically. For example, by doing
//! `ineed::written(...).fmt(...).then(...)` instead of `ineed::written(...).then(...).fmt(...)`.
//! In such case, if you provide a custom format for a specific promptable AND for the chain, with
//! conflicting rules, then the rules used are those defined for the specific promptable,
//! as they have more precedence.
