Enum FormatMode

pub enum FormatMode {
    Simple,
    SimpleRedacted,
    Stable,
}

Describes the context in which to print an AST.

Variants

Simple

Simple is the normal way of printing for human consumption. Identifiers are quoted only if necessary and sensative information is redacted.

SimpleRedacted

SimpleRedacted is like Simple, but strips out string and number literals. This makes SQL queries be “usage data”, rather than “customer data” according to our data management policy, allowing us to introspect it.

Stable

Stable prints out the AST in a form more suitable for persistence. All identifiers are quoted, even if not necessary. This mode is used when persisting table information to the catalog.

Trait Implementations

impl Clone for FormatMode

fn clone(&self) -> FormatMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FormatMode

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

Formats the value using the given formatter.

impl PartialEq for FormatMode

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