Enum QuoteStyle 

pub enum QuoteStyle {
    None,
    DoubleQuote,
    Backtick,
    Bracket,
}

How an identifier (column, table, alias) was quoted in the source SQL.

Used to preserve and transform quoting across dialects (e.g. backtick for MySQL/BigQuery → double-quote for PostgreSQL → bracket for T-SQL).

Variants

None

Bare / unquoted identifier

DoubleQuote

"identifier" — ANSI SQL, PostgreSQL, Oracle, Snowflake, etc.

Backtick

`identifier` — MySQL, BigQuery, Hive, Spark, etc.

Bracket

[identifier] — T-SQL / SQL Server

Implementations

impl QuoteStyle

pub fn for_dialect(dialect: Dialect) -> Self

Returns the canonical quoting style for the given dialect.

pub fn is_quoted(self) -> bool

Returns true when the identifier carries explicit quoting.

Trait Implementations

impl Clone for QuoteStyle

fn clone(&self) -> QuoteStyle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QuoteStyle

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

Formats the value using the given formatter.

impl Default for QuoteStyle

fn default() -> QuoteStyle

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for QuoteStyle

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for QuoteStyle

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for QuoteStyle

fn eq(&self, other: &QuoteStyle) -> 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 QuoteStyle

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for QuoteStyle

impl Eq for QuoteStyle

impl StructuralPartialEq for QuoteStyle
