Trait Implementations

[src]

impl Debug for Error

[src]

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter. Read more

[src]

impl Display for Error

[src]

pub fn fmt(&self, fmt: &mut Formatter<'_>) -> Result<(), Error>

[src]

impl Error for Error

[src]

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any. Read more

[src]

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred. Read more

1.0.0[src]

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
