Enum Var

pub enum Var {
    ERROR,
    Name(Token),
    TableAccess(TableAccess),
}

Possible ways in which a variable can be referenced.

Variants

ERROR

This Var had a syntax error.

Name(Token)

A simple reference to the variable.

local _ = foo

TableAccess(TableAccess)

local _ = t.foo

Trait Implementations

impl Clone for Var

fn clone(&self) -> Var

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Var

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

Formats the value using the given formatter.

impl Default for Var

fn default() -> Var

Returns the “default value” for a type.

impl GetRange for Var

fn get_range(&self) -> Result<Range, GetRangeError>

Get the range of the node. This will only fail if Cst.status is AstStatus::HasErrors.

impl Hash for Var

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 Ord for Var

fn cmp(&self, other: &Var) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl Parse<Expression> for Var

fn parse( token: Token, lexer: &mut Lexer<'_>, errors: &mut Vec<ParseError>, ) -> Option<Expression>

Try parsing the current item, starting from the passed token.

impl Parse<PrefixExp> for Var

fn parse( token: Token, lexer: &mut Lexer<'_>, errors: &mut Vec<ParseError>, ) -> Option<PrefixExp>

Try parsing the current item, starting from the passed token.

impl Parse for Var

fn parse( token: Token, lexer: &mut Lexer<'_>, errors: &mut Vec<ParseError>, ) -> Option<Self>

Try parsing the current item, starting from the passed token.

impl PartialEq for Var

fn eq(&self, other: &Var) -> 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 PartialOrd for Var

fn partial_cmp(&self, other: &Var) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Print for Var

fn print(&self) -> String

Prints the whole token including all surrounding spaces.

impl Eq for Var

impl StructuralPartialEq for Var
