Enum ExplainOption 

pub enum ExplainOption {
    Analyze {
        value: Option<Ident>,
        meta: Meta,
    },
    Verbose {
        value: Option<Ident>,
        meta: Meta,
    },
    Format {
        format: ExplainFormat,
        meta: Meta,
    },
    Other {
        name: Ident,
        value: Option<Ident>,
        meta: Meta,
    },
}

One option of an ExplainStatement.

ANALYZE/VERBOSE carry an optional boolean/word argument (ANALYZE, ANALYZE true) that is always absent in the legacy keyword-prefix spelling; FORMAT names an output format; any other PostgreSQL option (COSTS, BUFFERS, SETTINGS, WAL, TIMING, SUMMARY, …) rides Other with its optional argument.

Variants

Analyze

ANALYZE — actually run the statement and report real row counts and timings.

Fields

value: Option<Ident>

Value supplied by this syntax.

meta: Meta

Source location and node identity.

Verbose

VERBOSE — include additional plan detail.

Fields

value: Option<Ident>

Value supplied by this syntax.

meta: Meta

Source location and node identity.

Format

FORMAT <fmt> — select the plan output format.

Fields

format: ExplainFormat

The output format (TEXT/XML/JSON/YAML); see ExplainFormat.

meta: Meta

Source location and node identity.

Other

Any other named option, with its optional bareword/boolean argument.

Fields

name: Ident

Name referenced by this syntax.

value: Option<Ident>

Value supplied by this syntax.

meta: Meta

Source location and node identity.

Trait Implementations
