Struct lc3_ensemble::ast::Label

pub struct Label {
    pub name: String,
    /* private fields */
}

A label.

Alongside storing the name of the label, this struct also keeps track of where the label is in the assembly source code.

Fields

name: String

The label’s identifier

Implementations

impl Label

pub fn new(name: String, span: Range<usize>) -> Self

Creates a new label.

pub fn span(&self) -> Range<usize>

Returns the span of the label in assembly source code.

Trait Implementations

impl Clone for Label

fn clone(&self) -> Label

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Label

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

Formats the value using the given formatter.

impl Default for Label

fn default() -> Label

Returns the “default value” for a type.

impl Display for Label

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

Formats the value using the given formatter.

impl Hash for Label

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 Label

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

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TokenParse for Label

type Intermediate = Label

An intermediate to hold the match before it is converted to the actual component.

fn match_(m_token: Option<&Token>, span: Span) -> Result<Self, ParseErr>

Tries to match the next token to the given component, if possible.

fn convert(imed: Self::Intermediate, _span: Span) -> Result<Self, ParseErr>

Parses the intermediate into the given component, raising an error if conversion fails.

impl Eq for Label
