Enum artichoke::parser::State[][src]

pub enum State {
    ParseError,
    CodeTooLong,
    UnexpectedEnd,
    UnexpectedProgramEnd,
    UnexpectedRegexpBegin,
    UnterminatedBlock,
    UnterminatedHeredoc,
    UnterminatedString,
    Valid,
}

State shows whether artichoke can parse some code or why it cannot.

This enum only encapsulates whether artichoke can parse the code. It may still have syntactic or semantic errors.

Variants

ParseError

Internal parser error. This is a fatal error.

CodeTooLong

Code must be fewer than isize::MAX bytes.

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.

Implementations

impl State[src]

#[must_use]
pub const fn new() -> Self
[src]

Construct a new, default State.

#[must_use]
pub fn is_code_block_open(self) -> bool
[src]

Whether this variant indicates a code block is open.

This method can be used by a REPL to check whether to buffer code or begin a multi-line editing session before attempting to eval the code on an interpreter.

#[must_use]
pub fn is_recoverable_error(self) -> bool
[src]

Whether this variant is a recoverable error.

Recoverable errors should be handled by resetting the parser and input buffer.

#[must_use]
pub fn is_fatal(self) -> bool
[src]

Whether this variant is a fatal parse error.

Fatal parser states indicate the parser is corrupted and cannot be used again.
