Enum Literal 

pub enum Literal {
    Integer(i64),
    Float(f64),
    String(String),
    Bool(bool),
    Null,
    Vector(Vec<f32>),
    TextArray(Vec<Option<String>>),
    IntArray(Vec<Option<i32>>),
    BigIntArray(Vec<Option<i64>>),
    Interval {
        months: i32,
        days: i32,
        micros: i64,
        text: String,
    },
}

Variants

Integer(i64)

Float(f64)

String(String)

Bool(bool)

Null

Vector(Vec<f32>)

pgvector-style array literal, e.g. [1, 2.5, -3].

TextArray(Vec<Option<String>>)

TEXT[] value carried through the prepared-bind path (= ANY($1) has no column context to re-parse a {a,b} text form, so the array rides the AST natively).

IntArray(Vec<Option<i32>>)

INT[] value carried through the prepared-bind path.

BigIntArray(Vec<Option<i64>>)

BIGINT[] value carried through the prepared-bind path.

Interval

INTERVAL '<n> <unit> [<n> <unit> ...]' — calendar-aware span. Three independent dimensions: months (variable-length; year/month), days (fixed 86400 seconds at non-DST, but preserved as its own dimension so '1 day' ≠ '24 hours' stays distinguishable), and micros (sub-day; can carry). text keeps the original spelling so Display round-trips byte-for-byte. v7.37.5 β added the days field for PG parity.

Fields

months: i32

days: i32

micros: i64

text: String

Trait Implementations

impl Clone for Literal

fn clone(&self) -> Literal

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Literal

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

Formats the value using the given formatter.

impl Display for Literal

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

Formats the value using the given formatter.

impl PartialEq for Literal

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