Enum DataError 

pub enum DataError {
    IO(Error),
    Serde,
    Unknown,
    BadData,
    OutOfRange {
        index: usize,
        size: usize,
    },
}

Errors that can occur during data operations.

This enum encapsulates various error conditions that might arise during data reading, writing, and serialization operations.

Variants

IO(Error)

I/O error variant that occurs during file reading or writing operations.

Arguments

• source - The underlying IO error that triggered this error.

Serde

Serialization or deserialization error variant.

This error occurs when there is a failure during the serialization or deserialization of data.

Unknown

An unexpected or unknown error occurred during data operations.

This variant serves as a catch-all for errors not explicitly covered by other variants.

BadData

OutOfRange

An index does not address any element of the accessed collection.

Fields

index: usize

size: usize

Trait Implementations

impl Debug for DataError

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

Formats the value using the given formatter.

impl Display for DataError

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

Formats the value using the given formatter.

impl Error for DataError

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 DataError

fn from(source: Error) -> Self

Converts to this type from the input type.
