Implementations§

source§

impl<'a> ValueSet<'a>

source

pub fn callsite(&self) -> Identifier

Returns an Identifier that uniquely identifies the Callsite defining the fields this ValueSet refers to.

source

pub fn record(&self, visitor: &mut dyn Visit)

Visits all the fields in this ValueSet with the provided visitor.

source

pub fn len(&self) -> usize

Returns the number of fields in this ValueSet that would be visited by a given visitor to the ValueSet::record() method.

source

pub fn is_empty(&self) -> bool

Returns true if this ValueSet contains no values.
