the major trait defination

Required Methods

fn type_id(&self) -> TypeId

type id of current error type

fn get_top_msg(&self) -> String

convert the error of current level to string

fn get_lowest_msg(&self) -> String

convert the error of lowest level to string

fn get_lowest_err(&self) -> &dyn RucError

Get the original error object, used to match its original type by Any.

fn get_top_msg_with_dbginfo(&self) -> String

“error msg” + “debug info”

Provided Methods

fn type_ids(&self) -> Vec<TypeId>

type ids of errors of each level(from top to bottom).

fn lowest_type_id(&self) -> TypeId

get the type of the lowest(bottom) error

fn lowest_is_type(&self, e: &dyn Any) -> bool

check the type of the lowest error

fn contains_type(&self, e: &dyn Any) -> bool

check if an error exists in the error chain

fn msg_eq(&self, another: &dyn RucError) -> bool

compare two object

fn msg_has_overloop(&self, another: &dyn RucError) -> bool

check if any node from the error_chain matches the given error

fn cause(&self) -> Option<&dyn RucError>

point to a error which caused current error

fn stringify_chain(&self, prefix: Option<&str>) -> String

generate the final error msg

fn print_die(&self) -> !

Panic after printing error_chain

fn generate_log(&self, prefix: Option<&str>) -> String

Generate the log string

fn generate_log_custom(&self, prefix: Option<&str>) -> String

Generate the log string with custom mode

fn print(&self, prefix: Option<&str>)

Print log
