Struct StackError

pub struct StackError { /* private fields */ }

A simple error type that implements the ErrorStacks trait.

Implementations

impl StackError

pub fn new() -> Self

Creates a new empty StackError.

pub fn from_msg(error: impl Display + Send + Sync + 'static) -> Self

Creates a new StackError from any error message that implements Display + Send + Sync.

Trait Implementations

impl Debug for StackError

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

Formats the value using the given formatter.

impl Default for StackError

fn default() -> StackError

Returns the “default value” for a type.

impl Display for StackError

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

Formats the value using the given formatter.

impl Error for StackError

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

Returns the lower-level source of this error, if any.

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.
