Enum CheckpointError 

#[non_exhaustive]
pub enum CheckpointError {
    NotFound,
    StateTooLarge {
        size: usize,
        max: usize,
    },
    Serialization(String),
    Storage(String),
}

Errors that can occur during checkpoint operations.

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.

NotFound

The requested checkpoint was not found.

StateTooLarge

The serialized state exceeds the configured maximum size.

Fields

size: usize

The actual size of the serialized state.

max: usize

The maximum allowed size.

Serialization(String)

A serialization or deserialization error occurred.

Storage(String)

An error occurred in the underlying storage backend.

Trait Implementations

impl Debug for CheckpointError

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

Formats the value using the given formatter.

impl Display for CheckpointError

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

Formats the value using the given formatter.

impl Error for CheckpointError

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.
