Struct mz_expr::explain::HumanizedNotice

pub struct HumanizedNotice(bool);

A HumanizerMode that is ambiguous but allows us to print valid SQL statements, so it should be used in optimizer notices.

The inner parameter is true iff literals should be redacted.

Tuple Fields

0: bool

Implementations

impl HumanizedNotice

pub fn seq<'i, T>( &self, exprs: &'i [T], cols: Option<&'i Vec<String>>, ) -> impl Iterator<Item = HumanizedExpr<'i, T, Self>> + Clone

Trait Implementations

impl Clone for HumanizedNotice

fn clone(&self) -> HumanizedNotice

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HumanizedNotice

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

Formats the value using the given formatter.

impl HumanizerMode for HumanizedNotice

fn humanize_ident(_col: usize, ident: Ident, f: &mut Formatter<'_>) -> Result

Write ident.

fn new(redacted: bool) -> Self

Create a new instance of the optimizer mode with literal redaction determined by the redacted parameter value.

fn redacted(&self) -> bool

Return true iff literal redaction is enabled for this mode.

fn default() -> Self

Default implementation of a default constructor.

fn expr<'a, T>( &self, expr: &'a T, cols: Option<&'a Vec<String>>, ) -> HumanizedExpr<'a, T, Self>

Factory method that wraps the given expr and cols into a HumanizedExpr with the current mode.

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

Render a literal datum.
