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

ZeroReviewRounds

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

UnusableHeaderName

Fields

index: usize

name: String

UnusableHeaderValue

Names the header, never its value: the value is the half that carries a tenant or project token, and an error message is the one place it would escape into a terminal, a CI log or a bug report. The rule KeyCommandError already follows for a credential helper’s output.

Fields

index: usize

name: String

DuplicateHeaderName

Both spellings, never either value: which of the two is the credential is exactly what this error cannot know, so it quotes neither, the way UnusableHeaderValue above quotes none.

Fields

index: usize

first: String

second: String

UnknownBackend

Fields

index: usize

value: String

UnknownReasoningEffort

Fields

index: usize

value: String

AmbiguousApiKey

Both credential fields answer the same question, so a file setting both has said two things. Rejected rather than resolved by precedence: the user who wrote the command wrote it to be run, and a silent “the literal wins” leaves them debugging a stale credential the file says nothing about.

Fields

index: usize

EmptyApiKeyCommand

An argv with no first element names no program. Rejected at load because the alternative is discovering it inside the gate, at the point where there is nothing to run and nothing useful to say about why.

Fields

index: usize

BackendField

Fields

index: usize

backend: &'static str

field: &'static str

BackendMissingField

Fields

index: usize

backend: &'static str

field: &'static str

NoProviders(PathBuf)

NoEnabledProviders(PathBuf)

SiteOnlyField

Rejected rather than ignored, which is the one behaviour that would be worse than either: serde drops an unknown key without a word, so a developer reads refuse_markers in their own config, believes the repository is protected, and every review still ships its source. It is refused here rather than honoured because drep init gitignores this file - a copy of the control would be per-developer, and a refusal a developer can delete is not one.

Fields

path: PathBuf

field: &'static str

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.
