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

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

Variants

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

Methods

impl Problem[src]

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

Create Problem from any type implementing ToString or Display

pub fn from_error(error: &dyn Error) -> Problem[src]

Create Problem from type implement Error so that Error::cause is followed through

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
