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)

source

pub(crate) fn contains(&self, field: &Field) -> bool

Returns true if this ValueSet contains a value for the given Field.

source

pub(crate) fn is_empty(&self) -> bool

Returns true if this ValueSet contains no values.

source

pub(crate) fn field_set(&self) -> &FieldSet
