#[repr(transparent)]pub struct Error { /* private fields */ }
Expand description
A catboost error.
This is just a wrapper around an error message that
can only be constructed by reading the last error
message using the Error::fetch_catboost_error
method.
Implementations
sourceimpl Error
impl Error
sourcepub fn call<T>(ret_val: bool, val: T) -> Result<T>
pub fn call<T>(ret_val: bool, val: T) -> Result<T>
Shorthand for checking the result of a FFI call.
If the ret_val
is true
, the call was successfull and
Ok(val)
is returned. If the return value is false
,
the error message is fetched and returned.
sourcepub fn fetch_catboost_error() -> Self
pub fn fetch_catboost_error() -> Self
Fetch current error message from CatBoost
using the sys::GetErrorString
FFI call.
