[−][src]Enum problem::Problem

pub enum Problem {
    Cause(Cause, Option<String>),
    Context(String, Box<Problem>),
}

Error type that is not supposed to be handled but reported, panicked on or ignored

Variants

Cause(Cause, Option<String>)Context(String, Box<Problem>)

Methods

impl Problem[src]

pub fn from_message(
    msg: impl ToString
) -> Problem[src]

Create Problem from any type implementing ToString or Display

pub fn from_error<E>(error: E) -> Problem where
    E: Into<Box<dyn Error>>, [src]

Create Problem from types implementing Error so that Error::cause chain is followed through in the Display message

pub fn from_error_message<E>(error: &E) -> Problem where
    E: Error, [src]

Same as Problem::from_error but stores only final message and does not take ownership of the error

pub fn while_context(
    self,
    msg: impl ToString
) -> Problem[src]

Add context information to this Problem instance

pub fn backtrace(&self) -> Option<&str>[src]

Get backtrace associated with this Problem instance if available
