Enum SealError 

pub enum SealError<V>
where
    V: Identities,
{
    UnknownLineage(<V as Identities>::Lineage),
    GateCycle {
        cycle: Vec<Epoch<V>>,
    },
}

Why make_durable_through was refused. Nothing was sealed.

Variants

UnknownLineage(<V as Identities>::Lineage)

The lineage is not one the instance can answer for: the handle is another instance’s (DI-D-40).

GateCycle

The seal would close a gate cycle (DI-D-43): the writes it must wait for include a held write whose gate’s lineage reaching it needs, transitively, the seal to finish. Seal lower first, so the gates can be released.

Fields

cycle: Vec<Epoch<V>>

The cycle: each held write’s epoch followed by the gate it waits for. Each gate’s lineage reaching it needs the next write to complete, and the last gate’s needs the first’s.

Trait Implementations

impl<V> Error for SealError<V>

where V: Identities,

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
