Struct Error 

pub struct Error { /* private fields */ }

Errors that can occur when deserializing a type.

Implementations

impl Error

pub fn message(&self) -> &str

What went wrong

pub fn span(&self) -> Option<Range<usize>>

The start/end index into the original document where the error occurred

pub fn set_input(&mut self, input: Option<&str>)

Provide the encoded TOML the error applies to

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

Displays a TOML parse error

Example

TOML parse error at line 1, column 10 | 1 | 00:32:00.a999999 | ^ Unexpected a Expected digit While parsing a Time While parsing a Date-Time

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

Formats the value using the given formatter.

impl Error for Error

Available on crate feature serde only.

fn custom<T>(msg: T) -> Self

where T: Display,

Raised when there is general error when deserializing a type.

fn invalid_type(unexp: Unexpected<'_>, exp: &dyn Expected) -> Self

Raised when a Deserialize receives a type different from what it was expecting.

fn invalid_value(unexp: Unexpected<'_>, exp: &dyn Expected) -> Self

Raised when a Deserialize receives a value of the right type but that is wrong for some other reason.

fn invalid_length(len: usize, exp: &dyn Expected) -> Self

Raised when deserializing a sequence or map and the input data contains too many or too few elements.

fn unknown_variant(variant: &str, expected: &'static [&'static str]) -> Self

Raised when a Deserialize enum type received a variant with an unrecognized name.

fn unknown_field(field: &str, expected: &'static [&'static str]) -> Self

Raised when a Deserialize struct type received a field with an unrecognized name.

fn missing_field(field: &'static str) -> Self

Raised when a Deserialize struct type expected to receive a required field with a particular name but that field was not present in the input.

fn duplicate_field(field: &'static str) -> Self

Raised when a Deserialize struct type received more than one of the same field.

impl Error for Error

Available on non-crate feature std and crate feature serde 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 Hash for Error

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 IntoDeserializer<'_, Error> for Table

Available on crate feature serde only.

type Deserializer = Map<String, Value>

The type of the deserializer being converted into.

fn into_deserializer(self) -> Self

Convert this value into a deserializer.

impl IntoDeserializer<'_, Error> for Value

Available on crate feature serde only.

type Deserializer = Value

The type of the deserializer being converted into.

fn into_deserializer(self) -> Self

Convert this value into a deserializer.

impl<'de> IntoDeserializer<'de, Error> for Deserializer<'de>

Available on crate features parse and serde only.

type Deserializer = Deserializer<'de>

The type of the deserializer being converted into.

fn into_deserializer(self) -> Self::Deserializer

Convert this value into a deserializer.

impl<'de> IntoDeserializer<'de, Error> for Spanned<DeValue<'de>>

Available on crate features parse and serde only.

type Deserializer = ValueDeserializer<'de>

The type of the deserializer being converted into.

fn into_deserializer(self) -> Self::Deserializer

Convert this value into a deserializer.

impl<'de> IntoDeserializer<'de, Error> for Spanned<DeTable<'de>>

Available on crate features parse and serde only.

type Deserializer = Deserializer<'de>

The type of the deserializer being converted into.

fn into_deserializer(self) -> Self::Deserializer

Convert this value into a deserializer.

impl<'de> IntoDeserializer<'de, Error> for ValueDeserializer<'de>

Available on crate features parse and serde only.

type Deserializer = ValueDeserializer<'de>

The type of the deserializer being converted into.

fn into_deserializer(self) -> Self::Deserializer

Convert this value into a deserializer.

impl PartialEq for Error

fn eq(&self, other: &Error) -> 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 Eq for Error

impl StructuralPartialEq for Error

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.
