Struct AlterResult 

pub struct AlterResult(pub usize, pub Option<Vec<Metric>>, pub Option<Vec<LineageUpdate>>);

The AlterResult struct is used to represent the result of an alteration operation. It contains the number of operations performed and a vector of metrics that were collected during the alteration process.

Tuple Fields

0: usize

1: Option<Vec<Metric>>

2: Option<Vec<LineageUpdate>>

Implementations

impl AlterResult

pub fn empty() -> Self

pub fn count(&self) -> usize

pub fn update_lineage(&mut self, lineage: impl Into<LineageUpdate>)

pub fn merge(&mut self, other: AlterResult)
