Struct SerializableRetryOptions 

pub struct SerializableRetryOptions {
    pub(super) retry_max: u32,
    pub(super) backoff_base: Duration,
    pub(super) backoff_max: Duration,
    pub(super) backoff_factor: u32,
    pub(super) backoff_jitter: Ratio,
    pub(super) pg_stat_diag: bool,
}

Configuration for retrying transactions aborted by PostgreSQL serialization conflicts (error 40001). Under SERIALIZABLE isolation these aborts are expected and safe to retry from scratch.

Fields

retry_max: u32

Maximum number of retries on PostgreSQL serialization conflicts.

backoff_base: Duration

Initial delay before retrying after a PostgreSQL serialization conflict.

backoff_max: Duration

Maximum delay between retries after a PostgreSQL serialization conflict.

backoff_factor: u32

Multiplier applied to the backoff delay between successive retries.

backoff_jitter: Ratio

Backoff jitter as a ratio of the backoff delay, numerator:denominator.

pg_stat_diag: bool

When set, enable verbose diagnostic logging on PostgreSQL serialization conflicts. Each retried conflict spawns a background query against pg_stat_activity and pg_locks to log concurrent sessions and predicate locks. Off by default.

Trait Implementations

impl Args for SerializableRetryOptions

fn group_id() -> Option<Id>

Report the [ArgGroup::id][crate::ArgGroup::id] for this set of arguments
