Struct PgLsn 

pub struct PgLsn(/* private fields */);

PostgreSQL log sequence number.

PostgreSQL displays LSNs as X/Y, where X is the high 32 bits and Y is the low 32 bits in hexadecimal.

Implementations

impl PgLsn

pub const ZERO: Self

Zero LSN. Passing this to PostgreSQL asks the slot to start from its confirmed position.

pub const fn from_u64(value: u64) -> Self

pub const fn as_u64(self) -> u64

pub const fn is_zero(self) -> bool

pub fn parse(value: &str) -> CdcResult<Self>
