Struct TryNewError

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

Error returned when mapping operation fails.

Also returns the value passed in.

Implementations

impl<T: ?Sized> TryNewError<T>

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

pub fn into_parts(self) -> (T, Error)

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting
