# Parser.Many1

Repeats a parser at least once.

## Signatures

```ts
interface Many1<P extends Any> extends Parser<unknown> {
    readonly return: InputOf<this> extends infer Input extends string ? Many1Internal<P, Input> : never;
}
```

## Why

Required repetitions fail rather than returning an empty collection.

## Ownership and lifetime

TypeScript instantiates `Many1` while parsing a string-literal input; partial results and unconsumed text exist only in the resulting type.

## Property: return

Computes this type lambda's parse result for its current input.

## Property: return: Why

The local type-function protocol evaluates each parser combinator through this member without a parallel runtime object.

## Property: return: Ownership and lifetime

TypeScript evaluates `Many1.return` when the surrounding parser is applied; the associated result is erased and retains no input at runtime.
