Type of ParseError.

Implements std::fmt::Display to write a useful error message.

Variants

ExpectedTerminal(TerminalToken)

Expected a specific terminal token but got something else.

Example

function MyFunc { }
                ^ error

ExpectedCompound2(TerminalToken, TerminalToken)

Expected a specific compound terminal but got something else.

ExpectedCompound3(TerminalToken, TerminalToken, TerminalToken)

Expected a specific compound terminal but got something else.

ExpectedIdentifier

Expected an identifier but got something else.

Example

global var !?!?! = "guh??"
           ^ error

ExpectedLiteral

Expected a literal but got something else.

ExpectedExpression

Expected a token that starts an expression but got something else.

Example

int What = globalize_all_functions
           ^ error

ExpectedValue

Expected a token that starts a value in an expression but got something else.

Example

local sum = 1 + ?
                ^ error

ExpectedOperator

Expected an operator but got something else.

ExpectedPrefixOperator

Expected a prefix operator but got something else.

ExpectedPostfixOperator

Expected a postfix operator but got something else.

ExpectedBinaryOperator

Expected a binary operator but got something else.

ExpectedType

Expected a type but got something else.

Example

typedef Five 5
             ^ error

ExpectedTypeModifier

Expected a type modifier but got something else.

Example

typedef help table&-
                   ^ error

ExpectedTableSlot

Expected a token that starts a table slot but got something else.

Example

my_table = {
    class MyTableClass {}
    ^ error
}

ExpectedClassMember

Expected a token that starts a class member but got something else.

Example

class MyClass {
    globalize_all_functions
    ^ error
}

ExpectedStatement

Expected a token that starts a statement but got something else.

Example

> hey
^ error

ExpectedEndOfStatement

Expected a newline or semicolon to end a statement but got something else.

Example

{ 1 } + 2
      ^ error

ExpectedGlobalDefinition

Expected a token that starts a global definition but got something else.

Example

global if ()
       ^ error

IllegalLineBreak

Found a linebreak in a place where one is not allowed.

Precedence

An expression was not allowed due to precedence rules.

ExpectedSlot

Expected a slot in a class or table.

ExpectedStringLiteral

Expected a string literal.

Trait Implementations

impl Clone for ParseErrorType

fn clone(&self) -> ParseErrorType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseErrorType

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

Formats the value using the given formatter.

impl Display for ParseErrorType

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

Formats the value using the given formatter.

impl PartialEq for ParseErrorType

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