- Equivalence of type expressions can be understood in the following ways:
- Structural equivalence: Two type expressions are structurally equivalent if they are either the same basic type or formed by applying the same constructor to structurally equivalent types1.
- Name equivalence: Two type expressions are name equivalent if they are identical and can be represented by the same syntax tree with the same labels2.
- Type checking: When comparing expressions for equivalence, type checking ensures that the types of operands on both sides of the comparison operator are compatible, based on the type rules specified by the language3.

Type Equivalence - Western University
WEBWhen checking equivalence of named types, we have two possibilities. Name equivalence. Treat named types as basic types. Therefore two type expressions are name equivalent if and only if they are identical, that is if they can be represented by the same syntax tree, with the same labels. Structural equivalence.
WEB• Many languages: multiple ways to write a type •Write τ1 ≅τ2 when type expressions τi are equivalent types: Example: Extend tF with ( τ1*τ2)→τ3 ≅τ1→(τ2→τ3) – curried fcns applicable to pairs, vice versa – based on (compiler-inserted) bijection between types: curry and uncurry e : (τ1*τ2)→τ3 = λx:τ1 . λy:τ2 .

WEBTYPE EQUIVALENCE. Because of overloaded symbols and structured types, we will be concerned with the non trivial problem of type equivalence. That is, given two language constructs, decide whether they have the same type. We will use the notion of a type expression. TYPE EXPRESSION.
WEBCopyright c 2005 Christian Collberg. April 22, 2005. 1 Type Checking. In statically typed languages, when an object is de ned, we must also give its type: TYPE equivalence = type; TYPE subrange = [from..to]; TYPE enumeration = (id,id,...); TYPE array = ARRAY range OF type; TYPE record = RECORD field : type;
WEBTwo type expressions are name equivalent if and only if they are identical Structural equivalence: two expressions are structurally equivalent if and only if they have the same structure, that is, if they are formed by applying the same constructor to structurally equivalent type expressions. Example of Type Equivalence. In the Pascal fragment:

WEBType Equivalence. 5 Structural Type Equivalence. structural equivalence -- two types as the same if they consist of the same components. Example: TYPE T1 = RECORD a:INTEGER; b:ARRAY [0..10] OF CHAR; END; TYPE T2 = RECORD a:INTEGER; b:ARRAY [0..10] OF CHAR; END; Types T1 and T2 are equivalent.
Lecture 18: April 2, 2008
WEBType Equivalence. Name equivalence: two types are equivalent iff they have the same name. Structural equivalence: two types are equivalent iff they have the same structure. To test for structural equivalence, a compiler must encode the structure of a type in its representation. A tree (or type graph) is typically used. 4. Type Inference Rules.

WEBEquivalence of Type Expressions. • If two type expressions are equal then return a certain type else return type_error. Key Ideas: The main difficulty arises from the fact that most modern languages allow the naming of user-defined types. For instance, in C and C++ this is achieved by the typedef statement.

WEBMar 4, 2023 · When type expressions are represented by graphs, two types are structurally equivalent if and only if one of the following conditions is true: They are the same basic type. They are formed by applying the same constructor to structurally equivalent types. One is a type name that denotes the other.

structural equivalence vs name equivalence - Stack Overflow
WEBJan 29, 2016 · We now consider what it means to say that two types are "equal" (or equivalent). There are two standard ways to determine whether two types are considered the same: name equivalence and structural equivalence. Name equivalence is the most straightforward: two types are equal if, and only if, they have the same name.
