Struct Ident 

pub struct Ident {
    pub(crate) value: String,
    pub(crate) quote_style: Option<char>,
}

An identifier, decomposed into its value or character data and the quote style.

Fields

value: String

The value of the identifier without quotes.

quote_style: Option<char>

The starting quote if any. Valid quote characters are the single quote, double quote, backtick, and opening square bracket.

Implementations

impl Ident

pub fn new_unchecked<S>(value: S) -> Self

where S: Into<String>,

Create a new identifier with the given value and no quotes. the given value must not be a empty string.

pub fn with_quote_unchecked<S>(quote: char, value: S) -> Self

where S: Into<String>,

Create a new quoted identifier with the given quote and value. the given value must not be a empty string and the given quote must be in [‘'’, ‘“’, ‘`’, ‘[’].

pub fn with_quote_check<S>(quote: char, value: S) -> Result<Ident, ParserError>

where S: Into<String>,

Create a new quoted identifier with the given quote and value. returns ParserError when the given string is empty or the given quote is illegal.

pub fn real_value(&self) -> String

Value after considering quote style In certain places, double quotes can force case-sensitive, but not always e.g. session variables.

pub fn from_real_value(value: &str) -> Self

Convert a real value back to Ident. Behaves the same as SQL function quote_ident or QuoteIdent wrapper in common crate.

pub fn quote_style(&self) -> Option<char>

Trait Implementations

impl Clone for Ident

fn clone(&self) -> Ident

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Ident

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

Formats the value using the given formatter.

impl Display for Ident

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

Formats the value using the given formatter.

impl From<&str> for Ident

fn from(value: &str) -> Self

Converts to this type from the input type.

impl Hash for Ident

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 ParseTo for Ident

fn parse_to(parser: &mut Parser<'_>) -> ModalResult<Self>

impl PartialEq for Ident

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