Enum AppError 

pub enum AppError {
    Io {
        path: PathBuf,
        source: Error,
    },
    IoBare(Error),
    Credentials(String),
    Transport(String),
    Http {
        status: u16,
        body: String,
    },
    Schema(String),
    Json(Error),
    Toml(Error),
    Other(String),
}

Variants

Io

Local I/O failed (cache write, credentials read, theme file, etc.).

Fields

path: PathBuf

source: Error

IoBare(Error)

Generic I/O without a meaningful path (e.g. stdout writes).

Credentials(String)

A vendor’s credentials file is missing, unreadable, or malformed. Distinct from Io because the widget treats it as “user must re-auth” rather than a transient failure.

Transport(String)

HTTP request failed at the transport layer (DNS, TLS, timeout, connect). Maps to claudebar’s “HTTP 000” — show Loading…, don’t write .last_error, retry next tick.

Http

HTTP request reached the server but returned a non-2xx status. Carries the code + best-effort body so the widget can populate .last_error for the tooltip.

Fields

status: u16

body: String

Schema(String)

API returned 2xx but the body did not match our expected schema. Treated like an HTTP error for tooltip purposes, but logged separately because it signals undocumented-endpoint drift.

Json(Error)

JSON serialization/deserialization failure (config files, response bodies).

Toml(Error)

TOML config parse failure.

Other(String)

Catch-all for unexpected conditions (cache lock contention, etc.).

Implementations

impl AppError

pub fn io_at(path: impl Into<PathBuf>, source: Error) -> Self

Convenience for non-pathful I/O.

pub fn is_transient(&self) -> bool

True for transient network errors that the widget should hide behind a “Loading…” rather than a “⚠”.

Trait Implementations

impl Debug for AppError

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

Formats the value using the given formatter.

impl Display for AppError

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

Formats the value using the given formatter.

impl Error for AppError

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.

impl From<Error> for AppError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for AppError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for AppError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for AppError

Map a reqwest error into the right variant. Connection-class failures become Transport (transient); the rest become generic Http/Other.

fn from(err: Error) -> Self

Converts to this type from the input type.
