Struct FormatError 

pub struct FormatError(/* private fields */);

An error returned by formatting operations.

This can hold any error, allowing plugins to return their own error types, while still implementing std::error::Error so that consumers can convert it into their own error type.

Implementations

impl FormatError

pub fn new(error: impl Into<Box<dyn Error + Send + Sync + 'static>>) -> Self

Creates a new error from anything that can be turned into a boxed error (for example a String, &str, or any std::error::Error).

pub fn downcast_ref<E: Error + 'static>(&self) -> Option<&E>

Attempts to downcast the underlying error to a concrete type (ex. to check for a CriticalFormatError).

Trait Implementations

impl Debug for FormatError

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

Formats the value using the given formatter.

impl Display for FormatError

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

Formats the value using the given formatter.

impl Error for FormatError

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.
