Enum FormatError 

#[non_exhaustive]
#[repr(u8)]
pub enum FormatError {
    UnresolvedVariable = 0,
    UnknownFunction = 1,
    BadSelector = 2,
    BadOperand = 3,
    BadOption = 4,
    BadVariantKey = 5,
    UnsupportedOperation = 6,
    MessageFunctionError = 7,
    MissingFallbackVariant = 8,
    MissingMessage = 9,
    Malformed = 10,
}

An error reported while formatting. Formatting still produces output.

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.

UnresolvedVariable = 0

Unresolved Variable: no value for a variable.

UnknownFunction = 1

Unknown Function: the registry has no handler for a function.

BadSelector = 2

Bad Selector: a selector’s value does not support selection.

BadOperand = 3

Bad Operand: a function cannot take its operand.

BadOption = 4

Bad Option: an option or its value is not valid for the function.

BadVariantKey = 5

Bad Variant Key: a key a selector cannot compare against.

UnsupportedOperation = 6

Unsupported Operation: valid, but not supported by this handler or configuration (or past an implementation limit).

MessageFunctionError = 7

Any other failure of a function handler.

MissingFallbackVariant = 8

No variant matched — only a catalog built from an invalid model (no fallback variant, or key counts unlike the selector count) has one. The message formats as {�}.

MissingMessage = 9

The id is not in this catalog. Nothing is written.

Malformed = 10

The message’s catalog record is malformed: {�} in its place, and the message ends there.

Implementations

impl FormatError

pub const fn kind(self) -> Option<ErrorKind>

The MF2 error kind (mf2_model::ErrorKind); None for FormatError::MissingMessage and FormatError::Malformed, which are about the catalog, not the message.

Trait Implementations

impl Clone for FormatError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for FormatError

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 Eq for FormatError

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.

impl Hash for FormatError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FormatError

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

Equality operator ==.

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

Inequality operator !=.
