Struct StreamCheckpointError 

pub struct StreamCheckpointError(pub String);

Backend-level failure (IO, network, serialization). The contract is a newtype rather than a multi-variant enum because every checkpoint backend collapses its native error to a string at this boundary — callers never branch on the cause.

Trait Implementations

impl Debug for StreamCheckpointError

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

Formats the value using the given formatter.

impl Display for StreamCheckpointError

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

Formats the value using the given formatter.

impl Error for StreamCheckpointError

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.
