Struct ChainError 

pub struct ChainError {
    pub attempts: Vec<Attempt>,
    pub chain_len: usize,
}

No provider produced an answer, with what each one contributed.

attempts is never empty: ProviderChain::new rejects an empty chain, so a file that could not be analyzed always names at least one provider. It can be shorter than chain_len — a 401 at the head stops the chain, and the providers below it were never consulted.

chain_len is carried so the caller can tell “the only provider failed” from “a chain stopped early”, which are the same attempts.len() == 1 but very different questions for the user.

Fields

attempts: Vec<Attempt>

chain_len: usize
