Enum ReadError 

pub enum ReadError {
    Mdbx(MdbxError),
    Decoding(Box<dyn Error + Send + Sync + 'static>),
}

Error type for reading from the database.

This encapsulates errors that can occur during DB operations via Self::Mdbx as well as post-read during the TableObject decoding step via Self::Decoding.

For simplicity, the decoding error is boxed. Self::decoding can be used to create such an error from any error type fits the bounds. E.g. result.map_err(ReadError::decoding).

Variants

Mdbx(MdbxError)

Mdbx error during decoding.

Decoding(Box<dyn Error + Send + Sync + 'static>)

Type-associated error while decoding.

Implementations

impl ReadError

pub fn decoding<E>(err: E) -> Self

where E: Error + Send + Sync + 'static,

Creates a new decoding error from a boxed error.

Trait Implementations

impl Debug for ReadError

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

Formats the value using the given formatter.

impl Display for ReadError

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

Formats the value using the given formatter.

impl Error for ReadError

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<Box<dyn Error + Send + Sync>> for ReadError

fn from(source: Box<dyn Error + Send + Sync + 'static>) -> Self

Converts to this type from the input type.

impl From<MdbxError> for ReadError

fn from(source: MdbxError) -> Self

Converts to this type from the input type.
