Struct Annotation 

pub struct Annotation {
    pub loc: Loc,
    pub id: Identifier,
    pub value: Option<Expression>,
}

An annotation.

@<id>(<value>)

Fields

loc: Loc

The code location.

id: Identifier

The identifier.

value: Option<Expression>

The value.

Trait Implementations

impl Clone for Annotation

fn clone(&self) -> Annotation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CodeLocation for Annotation

fn loc(&self) -> Loc

Returns the code location of self.

impl Debug for Annotation

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

Formats the value using the given formatter.

impl Display for Annotation

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

Formats the value using the given formatter.

impl OptionalCodeLocation for Annotation

fn loc_opt(&self) -> Option<Loc>

Returns the optional code location of self.

impl PartialEq for Annotation

fn eq(&self, other: &Annotation) -> 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.
