Struct yottadb::YDBError

pub struct YDBError {
    pub message: Vec<u8>,
    pub status: i32,
    /* private fields */
}

An error returned by the underlying YottaDB library.

This error cannot be constructed manually.

Fields

message: Vec<u8>

YottaDB internally uses an error-handling mechanism similar to errno and perror. Since, in a threaded context, another error may occur before the application has a chance to call perror() (in YottaDB, $ZSTATUS), the stringified error must be returned at the same time as the status code.

status: i32

The status returned by a YottaDB function. This will be a YDB_ERR_* constant.

Trait Implementations

impl Clone for YDBError

fn clone(&self) -> YDBError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for YDBError

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

Formats the value using the given formatter.

impl Display for YDBError

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

Formats the value using the given formatter.

impl Error for YDBError

fn source(&self) -> Option<&(dyn Error + 'static)>

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, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl Hash for YDBError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<YDBError> for YDBError

fn eq(&self, other: &YDBError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
