Enum GraphError 

pub enum GraphError {
    LabelOverflow {
        used: usize,
    },
}

Errors returned by graph-engine operations.

Variants

LabelOverflow

The CSR’s edge-label id space is exhausted. Happens only when more than MAX_EDGE_LABELS distinct labels have been interned — in practice unreachable because the DSL ingress caps label length and realistic workloads use orders of magnitude fewer labels. Surfaced here so the failure mode is a typed error, not a silent wrap (the bug this crate was shipping before).

Fields

used: usize

Trait Implementations

impl Debug for GraphError

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

Formats the value using the given formatter.

impl Display for GraphError

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

Formats the value using the given formatter.

impl Error for GraphError

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.
