Enum Literal 

pub enum Literal {
    String(String),
    Number(String),
    HexString(String),
    HexNumber(String),
    BitString(String),
    ByteString(String),
    NationalString(String),
    Date(String),
    Time(String),
    Timestamp(String),
    Datetime(String),
    TripleQuotedString(String, char),
    EscapeString(String),
    DollarString(String),
    RawString(String),
}

Represent a SQL literal value.

Numeric values are stored as their original text representation (not parsed to i64/f64) so that precision, trailing zeros, and hex notation are preserved across round-trips.

Dialect-specific literal forms (triple-quoted strings, dollar-quoted strings, raw strings, etc.) each have a dedicated variant so that the generator can emit them with the correct syntax.

Variants

String(String)

Single-quoted string literal: 'hello'

Number(String)

Numeric literal, stored as the original text: 42, 3.14, 1e10

HexString(String)

Hex string literal: X'FF'

HexNumber(String)

Hex number: 0xA, 0xFF (BigQuery, SQLite style) - represents an integer in hex notation

BitString(String)

ByteString(String)

Byte string: b“…“ (BigQuery style)

NationalString(String)

National string: N’abc’

Date(String)

DATE literal: DATE ‘2024-01-15’

Time(String)

TIME literal: TIME ‘10:30:00’

Timestamp(String)

TIMESTAMP literal: TIMESTAMP ‘2024-01-15 10:30:00’

Datetime(String)

DATETIME literal: DATETIME ‘2024-01-15 10:30:00’ (BigQuery)

TripleQuotedString(String, char)

Triple-quoted string: “”“…”“” or ‘’‘…’‘’ Contains (content, quote_char) where quote_char is ‘“’ or ‘'’

EscapeString(String)

Escape string: E’…’ (PostgreSQL)

DollarString(String)

Dollar-quoted string: $$…$$ (PostgreSQL)

RawString(String)

Raw string: r“…“ or r’…’ (BigQuery, Spark, Databricks) In raw strings, backslashes are literal and not escape characters. When converting to a regular string, backslashes must be doubled.

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<'de> Deserialize<'de> for Literal

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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.

impl Serialize for Literal

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
