Trait stacked_errors::StackableErr

pub trait StackableErr {

    // Required methods
    fn stack_err<K: Into<ErrorKind>, F: FnOnce() -> K>(
        self,
        f: F
    ) -> Self::Output;

Conversion to and addition to the stack of an Error.

See the main crate documentation and implementation for examples.

Required Associated Types

type Output

Required Methods

fn stack_err<K: Into<ErrorKind>, F: FnOnce() -> K>(self, f: F) -> Self::Output

Pushes the result of f and location information to the stack

fn stack_err_locationless<K: Into<ErrorKind>, F: FnOnce() -> K>( self, f: F ) -> Self::Output

Pushes the result of f without location information

fn stack(self) -> Self::Output

Pushes just location information to the stack

fn stack_locationless(self) -> Self::Output

Only converts to Self::Output

This trait is not object safe.
