Struct ApplyWritesIncomplete 

pub struct ApplyWritesIncomplete {
    pub landed: usize,
    pub in_doubt: usize,
    pub total: usize,
    /* private fields */
}

How far a chunked applyWrites got before a chunk failed — carried by the error from every client’s apply_writes, and so from flush_read_states and add_subscriptions_bulk.

Read it with ApplyWritesIncomplete::of. In terms of the caller’s own input, in order:

• writes[..landed] were committed (each chunk was acknowledged);
• writes[landed..landed + in_doubt] were the failed call — usually not committed, but a timeout or a lost response cannot rule it out;
• everything after was never sent.

Display is the underlying failure’s message, with the progress appended when the batch had more than one chunk, so a log line still names the PDS’s reason. The failure’s own causes stay reachable through anyhow::Error::chain.

Fields

landed: usize

Writes committed, counted from the start of the input.

in_doubt: usize

Writes in the failed call, starting at landed.

total: usize

Writes in the whole batch.

Implementations

impl ApplyWritesIncomplete

pub fn of(err: &Error) -> Option<&Self>

The progress record an apply_writes error carries, if it has one.

pub fn cause(&self) -> &Error

The failure that stopped the run, as the client reported it.

Trait Implementations

impl Debug for ApplyWritesIncomplete

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

Formats the value using the given formatter.

impl Display for ApplyWritesIncomplete

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

Formats the value using the given formatter.

impl Error for ApplyWritesIncomplete

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>)
