Requiredint

Requiredint is a term used in software design and data validation to denote an integer field that must be supplied. It is not a standard primitive in mainstream programming languages, but it appears in schema definitions, contract-first API design, and form validation frameworks as a way to express mandatory presence alongside type requirements.

Definition and semantics

A Requiredint represents an integer value that is required for a given input, object, or record. Validation rules associated with Requiredint enforce two conditions: the field must be present, and the value must be an integer. Depending on the system, the value may also have range constraints (for example, within the bounds of a 32-bit signed integer), but the core requirement is presence and integer type.

Usage and implications

In practice, declaring a field as Requiredint communicates to clients and consumers that they must provide a numeric value for that field. Servers or validators will reject requests or data payloads that omit the field or supply a non-integer value. Some frameworks separate presence constraints from nullability; in such cases, Requiredint typically implies non-null and non-missing, with no default value unless the schema or API specifies one.

Examples and comparisons

An example field described as age: Requiredint implies that a payload must include age with an integer value, such as 25, and omits any allowance for missing age. This contrasts with Optionalint, which permits the field to be absent, and NullableInt, which allows null values in addition to integers.
