Union cases

Union case	Description
`NamedUnionCaseField(fieldName, caseIdRange)` Full Usage: `NamedUnionCaseField(fieldName, caseIdRange)` Parameters: fieldName : `string` caseIdRange : `range`	Completing union case field pattern (e.g. fun (Some (Value = v\| )) -> ) fieldName : `string` caseIdRange : `range`
`Other` Full Usage: `Other`	Any other position in a pattern that does not need special handling
`PositionalUnionCaseField(fieldIndex, isTheOnlyField, caseIdRange)` Full Usage: `PositionalUnionCaseField(fieldIndex, isTheOnlyField, caseIdRange)` Parameters: fieldIndex : `int option` - Position in the tuple. None if there is no tuple, with only one field outside of parentheses - `Some v\|` isTheOnlyField : `bool` - True when completing the first field in the tuple and no other field is bound - `Case (a\|)` but not `Case (a\|, b)` caseIdRange : `range` - Range of the case identifier	Completing union case field pattern (e.g. fun (Some v\| ) -> ) or fun (Some (v\| )) -> ). In theory, this could also be parameterized active pattern usage. fieldIndex : `int option` Position in the tuple. None if there is no tuple, with only one field outside of parentheses - `Some v\|` isTheOnlyField : `bool` True when completing the first field in the tuple and no other field is bound - `Case (a\|)` but not `Case (a\|, b)` caseIdRange : `range` Range of the case identifier
`RecordFieldIdentifier referencedFields` Full Usage: `RecordFieldIdentifier referencedFields` Parameters: referencedFields : `(string * range) list`	Completing a record field identifier in a pattern (e.g. fun { Field1 = a; Fie\| } -> ) referencedFields : `(string * range) list`
`UnionCaseFieldIdentifier(referencedFields, caseIdRange)` Full Usage: `UnionCaseFieldIdentifier(referencedFields, caseIdRange)` Parameters: referencedFields : `string list` caseIdRange : `range`	Completing union case field identifier in a pattern (e.g. fun (Case (field1 = a; fie\| )) -> ) referencedFields : `string list` caseIdRange : `range`
