Enum QueryBoundKind 

pub enum QueryBoundKind {
    Exact,
    ConservativeUpperBound,
    EnforcedRuntimeCap,
    EstimateOnly,
    Unavailable,
}

Quality of the bound carried into read admission.

Variants

Exact

Exact count known before execution.

ConservativeUpperBound

Conservative upper bound proven before execution.

EnforcedRuntimeCap

Runtime cap enforced by the executor while producing rows.

EstimateOnly

Planner estimate only; not safe as public admission authority.

Unavailable

No bound is available.

Implementations

impl QueryBoundKind

pub const fn as_str(self) -> &'static str

Return a stable lowercase diagnostic label for this bound quality.

pub const fn admits_public_read(self) -> bool

Return whether this bound kind is acceptable proof for public reads.

Trait Implementations

impl Clone for QueryBoundKind

fn clone(&self) -> QueryBoundKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for QueryBoundKind

impl Debug for QueryBoundKind

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

Formats the value using the given formatter.

impl Eq for QueryBoundKind

impl PartialEq for QueryBoundKind

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