Enum FlushTarget 

pub enum FlushTarget {
    Tables {
        table_keyword: TableKeyword,
        tables: ThinVec<ObjectName>,
        lock: Option<FlushTablesLock>,
        meta: Meta,
    },
    Options {
        options: ThinVec<FlushOption>,
        meta: Meta,
    },
}

What a FlushStatement flushes — MySQL’s mutually-exclusive flush_options split.

The {TABLE | TABLES} form (Tables) and the comma-separated keyword list (Options) are distinct grammar alternatives, not two shapes of one list: TABLES cannot appear inside the option list and the list members cannot follow TABLES (both ER_PARSE_ERROR on mysql:8.4.10), so they ride the axis as two variants rather than one option-soup list.

Variants

Tables

{TABLE | TABLES} [<tbl>[, ...]] [WITH READ LOCK | FOR EXPORT].

The table list may be empty (FLUSH TABLES, FLUSH TABLES WITH READ LOCK). FOR EXPORT requires a non-empty list — FLUSH TABLES FOR EXPORT is ER_PARSE_ERROR (ER_NO_TABLES_USED) on mysql:8.4.10 — while WITH READ LOCK admits the empty list; the parser enforces that boundary and never produces ForExport with an empty tables. The TABLE/TABLES spelling reuses the shared TableKeyword synonym tag.

Fields

table_keyword: TableKeyword

Whether the keyword was written TABLE or its TABLES synonym.

tables: ThinVec<ObjectName>

The comma-separated target table list (each schema-qualifiable); empty when no list was written.

lock: Option<FlushTablesLock>

The optional trailing WITH READ LOCK | FOR EXPORT lock clause.

meta: Meta

Source location and node identity.

Options

A comma-separated list of keyword flush targets (FLUSH LOGS, FLUSH PRIVILEGES, STATUS); see FlushOption. Always non-empty — the grammar’s flush_options_list carries at least one member.

Fields

options: ThinVec<FlushOption>

The keyword targets in source order.

meta: Meta

Source location and node identity.

Trait Implementations
