Enum WriteAllCacheCandidateSkipReason 

pub enum WriteAllCacheCandidateSkipReason {
    NotShared {
        output_count: usize,
    },
    MissingSqlText,
    IncompleteLineage,
    CoveredByDeeperSharedAlias {
        selected_table_id: u64,
    },
    AmbiguousDepth,
}

Reason a cache candidate was skipped by conservative write_all planning.

Variants

NotShared

Fewer than two selected outputs use this candidate.

Fields

output_count: usize

Number of selected outputs that use this candidate.

MissingSqlText

Retained SQL text was missing, so later replanning would be unsafe.

IncompleteLineage

Lineage was incomplete or could not be trusted.

CoveredByDeeperSharedAlias

A deeper shared alias is closer to all dependent outputs.

Fields

selected_table_id: u64

Table id of the selected deeper alias that covers this candidate.

AmbiguousDepth

The candidate’s relative depth could not be ordered deterministically.

Trait Implementations

impl Clone for WriteAllCacheCandidateSkipReason

fn clone(&self) -> WriteAllCacheCandidateSkipReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WriteAllCacheCandidateSkipReason

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

Formats the value using the given formatter.

impl Eq for WriteAllCacheCandidateSkipReason

impl PartialEq for WriteAllCacheCandidateSkipReason

fn eq(&self, other: &WriteAllCacheCandidateSkipReason) -> 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.
