Struct MultiJoinAnalysis 

pub struct MultiJoinAnalysis {
    pub joins: Vec<JoinAnalysis>,
    pub tables: Vec<String>,
}

Analysis result for multi-way JOINs (e.g., A JOIN B ... JOIN C ...).

Each step represents one left-deep join: step 0 joins the base table with the first right table, step 1 joins the result with the next right table, etc.

Fields

joins: Vec<JoinAnalysis>

Ordered join steps (left-to-right)

tables: Vec<String>

All referenced tables in order (base table first, then each right table)

Implementations

impl MultiJoinAnalysis

pub fn len(&self) -> usize

Number of join steps.

pub fn is_empty(&self) -> bool

Whether there are no join steps.

pub fn is_single(&self) -> bool

Whether this is a single join (backward-compatible case).

pub fn first(&self) -> Option<&JoinAnalysis>

The first join step (convenience for single-join queries).

Trait Implementations

fn clone(&self) -> MultiJoinAnalysis

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MultiJoinAnalysis

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

Formats the value using the given formatter.
