Enum ReplicaError 

pub enum ReplicaError {
    Unreachable(String),
    Halted {
        seq: u64,
        reason: String,
    },
    Gap {
        window_base: u64,
    },
}

Why a round stopped.

Variants

Unreachable(String)

The home could not be reached or answered something this round cannot use. Transient: the next round tries again.

Halted

A page failed a check, an entry could not be folded, or the home changed key. Replication stops at seq for the life of the process; everything before it is kept and served.

Fields

seq: u64

The first seq not taken.

reason: String

Why.

Gap

The home evicted entries this seed needs and has no persisted log to serve them from. Replication stops; see the module docs.

Fields

window_base: u64

Where the home’s window resumes.

Implementations

impl ReplicaError

pub fn is_halt(&self) -> bool

Whether this stops replication for the life of the process, as opposed to a round the next one retries.

Trait Implementations

impl Clone for ReplicaError

fn clone(&self) -> ReplicaError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ReplicaError

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

Formats the value using the given formatter.

impl Display for ReplicaError

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

Formats the value using the given formatter.

impl PartialEq for ReplicaError

fn eq(&self, other: &ReplicaError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
