Struct Ident

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

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§

source§

impl Ident

source

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.

source

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 [‘'’, ‘“’, ‘`’, ‘[’].

source

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.

source

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.

source

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