Enum Format

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

Available on crate feature formatting only.

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.

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

Available on crate feature std only.

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.

impl From<Error> for Format

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<Format> for Error

fn from(original: Format) -> Self

Converts to this type from the input type.

impl TryFrom<Error> for Format

type Error = DifferentVariant

The type returned in the event of a conversion error.

fn try_from(err: Error) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Format> for Error

type Error = DifferentVariant

The type returned in the event of a conversion error.

fn try_from(err: Format) -> Result<Self, Self::Error>

Performs the conversion.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
