Enum TableKey

pub enum TableKey {
    ERROR,
    UndefinedNumber(u32),
    UndefinedString(SmolStr),
    Simple(Token),
    Expression(Bracketed<Pointer<Expression>>),
    Type(Bracketed<Pointer<TypeValue>>),
}

A possible key entry in a table. The key is usually a string, but it can be a value (from an expression) in tables or a type in type definitions.

local t = {
    -- The normal string key.
    foo = "foo",

    -- A Value key, it's still a string, but what's inside [] is
    -- always counted as an expression, even if simple.
    ["bar"] = "bar",
}

type T = {
    -- The normal string key.
    foo: "foo",

    -- A Type key, it indicates that the key can be any string, not the word "string".
    [string]: number,
}

Variants

ERROR

This TableKey had a syntax error.

UndefinedNumber(u32)

Cases in which a key in a table expression wasn’t provided, it’s guessed as a number in that case.

UndefinedString(SmolStr)

Cases in which a key in a type expression wasn’t provided, it’s guessed as number. It has no other possible values than number.

Simple(Token)

Simple key

Expression(Bracketed<Pointer<Expression>>)

An expression, can only be used in definitions and not in types.

Type(Bracketed<Pointer<TypeValue>>)

A type definition, can only be used in other types and not definitions.

Trait Implementations

impl Clone for TableKey

fn clone(&self) -> TableKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TableKey

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

Formats the value using the given formatter.

impl Default for TableKey

fn default() -> TableKey

Returns the “default value” for a type.

impl GetRange for TableKey

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 TableKey

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 TableKey

fn cmp(&self, other: &TableKey) -> 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<TableAccessKey> for TableKey

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

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

impl ParseWithArgs<bool> for TableKey

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

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

impl PartialEq for TableKey

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

fn partial_cmp(&self, other: &TableKey) -> 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 TableKey

fn print(&self) -> String

Prints the whole token including all surrounding trivia.

fn print_final_trivia(&self) -> String

Prints only the very final trivia. Used for the default implementation of Print::print, which just joins Print::print_without_final_trivia and this function.

fn print_without_final_trivia(&self) -> String

Prints the whole token including all surrounding trivia, excluding the very last trailing trivia.

impl Eq for TableKey

impl StructuralPartialEq for TableKey
