pub struct TryNewError<T: ?Sized> { /* private fields */ }

Error returned when mapping operation fails.

Also returns the value passed in.

pub fn value(&self) -> &T

A reference to the value

pub fn value_mut(&mut self) -> &mut T

A mutable reference to the value

pub fn error(&self) -> &Error

A reference to the IO error

pub fn into_error_box(self: Box<Self>) -> Box<Error>

Consume a boxed instance and return the boxed IO error.

impl<T> TryNewError<T>

pub fn into_inner(self) -> T

Consume into the contained value

pub fn into_error(self) -> Error

Consume into the IO error
