Enum mruby_bin::parser::State

pub enum State {
    ParseError,

}

State shows whether mruby can parse some code or why it cannot. This enum only encapsulates whether mruby can parse the code. It may still have syntactic or semantic errors.

Variants

ParseError

Internal parser error. This is a fatal error.

UnexpectedEnd

The code has too many end statements.

UnexpectedProgramEnd

The code has unclosed blocks.

UnexpectedRegexpBegin

The current expression is an unterminated Regexp.

UnterminatedBlock

The current expression is an unterminated block.

UnterminatedHeredoc

The current expression is an unterminated heredoc.

UnterminatedString

The current expression is an unterminated String.

Valid

Code is valid and fit to eval.

Methods

impl State

pub fn is_code_block_open(&self) -> bool

Does this state indicate a code block is open? Used by the REPL to know whether to buffer code before attempting to eval it on the interpreter.

Trait Implementations

impl Eq for State

impl PartialEq<State> for State

fn eq(&self, other: &State) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Clone for State

fn clone(&self) -> State

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for State

fn default() -> Self

Returns the "default value" for a type.

impl Debug for State

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

Formats the value using the given formatter.
