Struct ExplainAccessDecisionV1 

pub struct ExplainAccessDecisionV1 {
    pub schema_version: u32,
    pub selected: ExplainSelectedAccessV1,
    pub candidates: Vec<ExplainAccessCandidateV1>,
    pub alternatives: Vec<ExplainEligibleAlternativeV1>,
    pub rejections: Vec<ExplainRejectedIndexV1>,
    pub residual: ExplainResidualSummaryV1,
}

Stable JSON-facing access-decision projection for logical EXPLAIN.

This DTO is derived from the planner-owned access-choice snapshot and the selected explain access path. It is not an optimizer model and does not participate in access selection.

Fields

schema_version: u32

Schema version for this access-decision payload shape.

selected: ExplainSelectedAccessV1

Selected access path summary.

candidates: Vec<ExplainAccessCandidateV1>

Planner candidate summaries recorded for the selected access family.

alternatives: Vec<ExplainEligibleAlternativeV1>

Eligible alternatives not selected by the planner.

rejections: Vec<ExplainRejectedIndexV1>

Rejected index candidates and planner-owned reason strings.

residual: ExplainResidualSummaryV1

Residual-work summary for the selected route when available.

Trait Implementations

impl Clone for ExplainAccessDecisionV1

fn clone(&self) -> ExplainAccessDecisionV1

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExplainAccessDecisionV1

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

Formats the value using the given formatter.

impl PartialEq for ExplainAccessDecisionV1

fn eq(&self, other: &ExplainAccessDecisionV1) -> 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.
