Struct Problem

pub struct Problem { /* private fields */ }

Wraps error, context and backtrace information and formats it for display. Data is heap allocated to avoid type parameters or lifetimes.

Implementations

impl Problem

pub fn from_error(error: impl Into<Box<dyn Error>>) -> Problem

Create Problem from types implementing Into<Box<dyn Error>> (including String and &str) so that Error::cause chain is followed through in the Display message

pub fn from_error_message(error: &impl Error) -> Problem

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

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

Get backtrace associated with this Problem instance if available

pub fn into_error(self) -> Error

Wraps Problem into type implementing Error trait
