Available on (crate features formatting or parsing) and crate feature alloc only.

The format description provided was not valid.

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.

UnclosedOpeningBracket

There was a bracket pair that was opened but not closed.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

index: usize

The zero-based index of the opening bracket.

InvalidComponentName

A component name is not valid.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

name: String

The name of the invalid component name.

index: usize

The zero-based index the component name starts at.

InvalidModifier

A modifier is not valid.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

value: String

The value of the invalid modifier.

index: usize

The zero-based index the modifier starts at.

MissingComponentName

A component name is missing.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

index: usize

The zero-based index where the component name should start.

MissingRequiredModifier

A required modifier is missing.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

name: &'static str

The name of the modifier that is missing.

index: usize

The zero-based index of the component.

Expected

Something was expected, but not found.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

what: &'static str

What was expected to be present, but wasn’t.

index: usize

The zero-based index the item was expected to be found at.

NotSupported

Certain behavior is not supported in the given context.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

what: &'static str

The behavior that is not supported.

context: &'static str

The context in which the behavior is not supported.

index: usize

The zero-based index the error occurred at.

Trait Implementations

impl Clone for InvalidFormatDescription

fn clone(&self) -> InvalidFormatDescription

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for InvalidFormatDescription

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

Formats the value using the given formatter.

impl Display for InvalidFormatDescription

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

Formats the value using the given formatter.

impl Error for InvalidFormatDescription

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<InvalidFormatDescription> for Error

fn from(original: InvalidFormatDescription) -> Self

Converts to this type from the input type.

impl PartialEq for InvalidFormatDescription

fn eq(&self, other: &InvalidFormatDescription) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<Error> for InvalidFormatDescription

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.
