| [EvoluTypeSymbol] | readonly | true | - | Type.[EvoluTypeSymbol] | packages/common/src/Type.ts:169 |
| element | readonly | ElementType | - | - | packages/common/src/Type.ts:2149 |
| Error | public | ArrayError<InferError<ElementType>> | The specific error introduced by this Type. ### Example type StringError = typeof String.Error; | Type.Error | packages/common/src/Type.ts:94 |
| Errors | readonly | | ArrayError<InferError<ElementType>> | ArrayError<InferParentError<ElementType>> | Error | ParentError ### Example type StringParentErrors = typeof String.Errors; | Type.Errors | packages/common/src/Type.ts:235 |
| from | readonly | (value) => Result<readonly InferType<ElementType>[], | ArrayError<InferError<ElementType>> | ArrayError<InferParentError<ElementType>>> | Creates T from an Input value. This is useful when we have a typed value. from is a typed alias of fromUnknown. | Type.from | packages/common/src/Type.ts:109 |
| fromParent | readonly | (value) => Result<readonly InferType<ElementType>[], ArrayError<InferError<ElementType>>> | Creates T from Parent type. This function skips parent Types validations/transformations when we have already partially validated/transformed value. For example, TrimString.from checks whether a value is a string and trims it. If we only want to trim a string, we can use fromParent. ### Example // string & Brand<"Trimmed"> const value = TrimString.fromParent("a ").value; // as efficient as foo.trim() | Type.fromParent | packages/common/src/Type.ts:143 |
| fromUnknown | readonly | (value) => Result<readonly InferType<ElementType>[], | ArrayError<InferError<ElementType>> | ArrayError<InferParentError<ElementType>>> | Creates T from an unknown value. This is useful when a value is unknown. | Type.fromUnknown | packages/common/src/Type.ts:116 |
| Input | public | readonly InferInput<ElementType>[] | The type expected by from and fromUnknown. ### Example type StringInput = typeof String.Input; | Type.Input | packages/common/src/Type.ts:92 |
| is | readonly | (value) => value is readonly InferType<ElementType>[] | A type guard that checks whether an unknown value satisfies the Type. ### Example const value: unknown = "hello"; if (String.is(value)) { // TypeScript now knows valueis astring here. console.log("This is a valid string!"); } const strings: unknown[] = [1, "hello", true, "world"]; const filteredStrings = strings.filter(String.is); console.log(filteredStrings); // ["hello", "world"] | Type.is | packages/common/src/Type.ts:167 |
| name | readonly | "Array" | - | Type.name | packages/common/src/Type.ts:100 |
| Parent | public | readonly InferParent<ElementType>[] | The parent type. ### Example type StringParent = typeof String.Parent; | Type.Parent | packages/common/src/Type.ts:96 |
| ParentError | public | ArrayError<InferParentError<ElementType>> | The parent's error. ### Example type StringParentError = typeof String.ParentError; | Type.ParentError | packages/common/src/Type.ts:98 |
| to | readonly | (value) => readonly InferInput<ElementType>[] | The opposite of from and fromUnknown. This is useful to transform T back to its Input representation. For refine, it only removes the brand. For transform, it changes value. | Type.to | packages/common/src/Type.ts:125 |
| toParent | readonly | (value) => readonly InferParent<ElementType>[] | The opposite of fromParent. | Type.toParent | packages/common/src/Type.ts:146 |
| Type | readonly | readonly InferType<ElementType>[] | The type this Type resolves to. ### Example type String = typeof String.Type; | Type.Type | packages/common/src/Type.ts:180 |
