Struct GuardedWriteFailure 

pub struct GuardedWriteFailure {
    pub entry_index: Option<usize>,
    pub missing_source: Option<Uuid>,
    pub missing_target: Option<Uuid>,
}

A guarded edge write (link/link_many) was refused because one or both endpoints no longer existed at write time. Names the exact endpoint(s) missing instead of a generic “source or target” message, and, for a batch write, which entry in the batch failed first.

Fields

entry_index: Option<usize>

Index of the failing entry within a link_many batch. None for the singleton link path, which has no batch to index into.

missing_source: Option<Uuid>

The source endpoint id, present only when it is the (or one of the) missing endpoint(s).

missing_target: Option<Uuid>

The target endpoint id, present only when it is the (or one of the) missing endpoint(s).

impl Eq for GuardedWriteFailure

impl Error for GuardedWriteFailure

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
