Struct CatBoostError 

pub struct CatBoostError { /* private fields */ }

Implementations

impl CatBoostError

pub fn check_return_value(ret_val: bool) -> CatBoostResult<()>

Check the return value from an CatBoost FFI call, and return the last error message on error. Return values of true are treated as success, returns values of false are treated as errors.

Trait Implementations

impl Debug for CatBoostError

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

Formats the value using the given formatter.

impl Display for CatBoostError

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

Formats the value using the given formatter.

impl Error for CatBoostError

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 PartialEq for CatBoostError

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

Tests for self and other values to be equal, and is used by ==.

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

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