Enum ErrorKind 

#[non_exhaustive]
pub enum ErrorKind {
    RateLimited,
    BudgetSpent,
    Network,
    Timeout,
    Server,

    CircuitOpen,

Exactly what went wrong, for front ends that word or localise it themselves. Finer than ErrorCategory; new kinds may be added.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

RateLimited

BudgetSpent

The provider’s usage budget is spent until it resets.

Network

Timeout

Server

The provider answered with a server error.

NotCached

Offline, and not in the cache.

CircuitOpen

Skipped after repeated failures, for a cooldown.

KeyRejected

The API key (or other credential) was rejected.

NotFound

BadRequest

Unsupported

Decode

The answer couldn’t be understood.

InvalidId
