Enum CoreError 

pub enum CoreError {
    Cancelled(Option<String>),
    Encoding(String),
    MissingEnv(String),
    Io(Error),
}

The closed error vocabulary for indusagi-core primitives.

Variants

Cancelled(Option<String>)

A cooperative cancellation was observed. Carries an optional reason for diagnostics; the byte-exact Display is cancelled when no reason is set (mirrors the Python CancelledByToken default message).

Encoding(String)

A value could not be canonically encoded for hashing (a non-finite number is not an error — it folds to null — so this is reserved for shapes the encoder genuinely cannot represent).

MissingEnv(String)

A required environment variable was absent or empty.

Io(Error)

A filesystem location could not be prepared.

Implementations

impl CoreError

pub fn cancelled() -> Self

Construct a CoreError::Cancelled with no reason.

pub fn cancelled_with(reason: impl Into<String>) -> Self

Construct a CoreError::Cancelled carrying reason.

pub fn is_cancelled(&self) -> bool

True iff this is a cancellation error. Lets call sites branch on “was this a cancel?” without a full match.

impl CoreError

pub fn detail(&self) -> impl Display + '_

The human-readable detail, used when a caller flattens this into its own String-carrying typed error.

Trait Implementations

impl Debug for CoreError

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

Formats the value using the given formatter.

impl Display for CoreError

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

Formats the value using the given formatter.

impl Error for CoreError

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 CoreError

fn from(source: Error) -> Self

Converts to this type from the input type.
