}Expand description
A db_wave_file row’s size and counter columns.
Fields§
§size: i64§modts: i64§incarnation: Option<Vec<u8>>Random per-row identity (insert trigger); differs across a delete + re-create even when every other column matches.
rev: i64Bumped by every write that rewrites existing bytes (not appends).

Source§impl Row
impl Row
Sourcepub fn counter(&self) -> Option<(String, LineCount)>
pub fn counter(&self) -> Option<(String, LineCount)>
The epoch, if it is valid: present, and the file has not been written since by anything that doesn’t maintain it.
Sourcepub fn behind(&self) -> Option<Behind>
pub fn behind(&self) -> Option<Behind>
An epoch that is behind but still describes the file’s start: nothing
rewrote a byte since it was counted (rev unchanged), and the file
only grew past lines_size. Such an epoch is caught up, not dropped
(see the module doc). None for a missing, torn or rewritten epoch.
Sourcepub fn has_epoch_columns(&self) -> bool
pub fn has_epoch_columns(&self) -> bool
Whether any counter column is set — an epoch to drop when invalid.
fn state(&self) -> LineState
