Enum Error 

pub enum Error {
    Api(ApiError),
    Http(Error),
    Json(Error),
    Internal(String),
}

Top-level error type for the Todoist API client.

This wraps all possible errors that can occur when using the client, including API-specific errors, network errors, and serialization errors.

Variants

Api(ApiError)

An API-specific error (auth failure, rate limiting, validation, etc.)

Http(Error)

An HTTP request/response error from reqwest.

Json(Error)

JSON serialization/deserialization error.

Internal(String)

Internal/unexpected error.

Implementations

impl Error

pub fn is_retryable(&self) -> bool

Returns true if this error is potentially retryable.

pub fn is_invalid_sync_token(&self) -> bool

Returns true if this error indicates an invalid sync token.

This is used to detect when the API rejects a sync token, which means the client should fall back to a full sync with sync_token='*'.

pub fn exit_code(&self) -> i32

Returns the appropriate CLI exit code for this error.

Exit codes follow the spec:

• 2: API error (auth failure, not found, validation error)
• 3: Network error (connection failed, timeout)
• 4: Rate limited (with retry-after information)

pub fn as_api_error(&self) -> Option<&ApiError>

Returns the underlying API error if this is an API error variant.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
