Enum Format

#[non_exhaustive]
pub enum Format {
    InsufficientTypeInformation,
    InvalidComponent(&'static str),
    StdIo(Error),
}

An error occurred when formatting.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InsufficientTypeInformation

The type being formatted does not contain sufficient information to format a component.

InvalidComponent(&'static str)

The component named has a value that cannot be formatted into the requested format.

This variant is only returned when using well-known formats.

StdIo(Error)

A value of std::io::Error was returned internally.

Implementations

impl Format

#[doc(hidden)] pub fn into_invalid_serde_value<S: Serializer>(self) -> S::Error

Obtain an error type for the serializer.

Trait Implementations

impl Debug for Format

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

Formats the value using the given formatter.

impl Display for Format

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

Formats the value using the given formatter.

impl Error for Format

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

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

#[doc(hidden)] fn type_id(&self, _: Internal) -> TypeId

where Self: 'static,

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

Gets the TypeId of self.

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.

impl From<Error> for Format

fn from(err: Error) -> Self
