What went wrong reading or validating the configuration.

Variants

Io(PathBuf, Error)

Parse(PathBuf, String)

EnvVarUnset(String, String)

EnvVarNotUnicode(String, String)

Temperature

The index is the zero-based position in the file; the message renders it one-based, and says “in file order” because the chain numbers only the enabled entries - with a disabled head the two differ, and [[llm]] #1 meaning different tables in the same file is worse than either convention alone.

Fields

index: usize

temperature: f32

ZeroConcurrency

max_concurrent = 0 builds a semaphore with no permits, so every request waits for one forever. Rejected at load rather than clamped: a silent bump to 1 would run a gate at a concurrency the user did not ask for, and the alternative - the documented “callers are expected to set a positive value” - is a hang with no message at all.

Fields

index: usize

ZeroTimeout

Fields

index: usize

ZeroMaxTokens

Fields

index: usize

UnknownProtocol

Rejected rather than defaulted: falling back to openai would post chat-completions bytes to a /messages endpoint, and the resulting 404 reads as “the provider is down” rather than “this line has a typo”.

Fields

index: usize

value: String

UnknownBackend

Fields

Trait Implementations

impl Debug for ConfigError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ConfigError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ConfigError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
