Struct Tag 

pub(crate) struct Tag {
    pub(crate) name: SymbolName,
    pub(crate) span: SimpleSpan,
}

A “Tag” is a symex used as a name for a place in a program. A tag is always terminated by an arrow (“->”) and [in the symbol table] it set to the numerical location of the word that it tags. [from section 6-2.2 of the User’s Handbook].

Fields

name: SymbolName

span: SimpleSpan

Implementations

impl Tag

fn symbol_uses( &self, block_id: BlockIdentifier, block_offset: Unsigned18Bit, ) -> impl Iterator<Item = Result<(SymbolName, SimpleSpan, SymbolUse), InconsistentSymbolUse>> + use<>

Trait Implementations

impl Clone for Tag

fn clone(&self) -> Tag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Tag

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

Formats the value using the given formatter.

impl Ord for Tag

fn cmp(&self, other: &Self) -> Ordering

Ordering for tags ignores the span.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Tag

fn eq(&self, other: &Tag) -> 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 PartialOrd for Tag

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

Ordering for tags ignores the span.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
