Struct ZvecError 

pub struct ZvecError {
    pub code: ErrorCode,
    pub message: Option<String>,
}

Error returned by fallible safe wrappers over the zvec C API.

The message field, when present, is the last-error message retrieved via sys::zvec_get_last_error at the time the error was constructed.

Fields

code: ErrorCode

message: Option<String>

Implementations

impl ZvecError

pub fn from_code(code: Type) -> Self

Construct an error from a raw code, pulling the current thread-local message out of the C API if one is set.

pub fn with_message(code: ErrorCode, message: impl Into<String>) -> Self

Construct an error with a static message (used for cases where the C API did not provide a detailed message, e.g. NULL-returning creators).

Trait Implementations

impl Clone for ZvecError

fn clone(&self) -> ZvecError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ZvecError

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

Formats the value using the given formatter.

impl Display for ZvecError

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

Formats the value using the given formatter.

impl Error for ZvecError

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.
