Enum TokenType

pub enum TokenType {
    Letter,
    G,
    M,
    T,
    Percent,
    Number,
    Comment,
    Slash,
    MinusSign,
    PlusSign,
    Newline,
    Unknown,
    Eof,
}

Lexer token kind. Used by the parser and in Diagnostics::emit_unexpected to report what was expected.

Variants

Letter

Single alphabetic character that is not G, M, or T (e.g. N, O, X).

G

G code letter (case-insensitive in source).

M

M code letter (case-insensitive in source).

T

T code letter (case-insensitive in source).

Percent

Program delimiter % (RS-274 / ISO 6983).

Number

Numeric literal.

Comment

Comment (semicolon or parentheses).

Slash

A / is used to indicate a deleted block.

MinusSign

Minus sign.

PlusSign

Plus sign.

Newline

Newline.

Unknown

Unrecognised token.

Eof

Virtual: expected end of input (no more tokens).

Implementations

impl TokenType

pub const fn as_str(self) -> &'static str

Get the human-friendly name for this token type.

Trait Implementations

impl Clone for TokenType

fn clone(&self) -> TokenType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TokenType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TokenType

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for TokenType

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

Formats the value using the given formatter.

impl Hash for TokenType

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 PartialEq for TokenType

fn eq(&self, other: &TokenType) -> 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 Serialize for TokenType

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for TokenType

impl Eq for TokenType

impl StructuralPartialEq for TokenType
