    },
}

A unified error type for all toon-macro operations.

Variants

Serialize(String)

Error during TOON serialization.

Deserialize(String)

Error during TOON deserialization/parsing.

InvalidTable(String)

Invalid TOON table structure.

MissingColumn(&'static str)

A required column is missing from the table.

ConversionError(String)

Error converting between types.

InvalidType

Invalid value type encountered.

Fields

expected: &'static str

The expected type name.

got: String

The actual type name.

RowOutOfBounds

Row index out of bounds.

Fields

index: usize

The requested index.

len: usize

The number of rows in the table.

ColumnOutOfBounds

Column index out of bounds.

Fields

index: usize

The requested index.

len: usize

The number of columns in the table.

Implementations

impl Error

pub fn serialize<S: Into<String>>(msg: S) -> Self

Create a serialization error from a message.

pub fn deserialize<S: Into<String>>(msg: S) -> Self

Create a deserialization error from a message.

pub fn invalid_table<S: Into<String>>(msg: S) -> Self

Create an invalid table error.

pub fn missing_column(name: &'static str) -> Self

Create a missing column error.

pub fn conversion<S: Into<String>>(msg: S) -> Self

Create a conversion error.

pub fn invalid_type(expected: &'static str, got: impl Debug) -> Self

Create an invalid type error.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(err: Error) -> Self

Converts to this type from the input type.
