# Function: grantFits()

```ts
function grantFits(
   grant, 
   cmd, 
   args, 
   opaque?
): boolean;
```

Defined in: [packages/core/src/space/grants.ts:206](https://github.com/leifriksheim/minca/blob/main/core/src/space/grants.ts#L206)

Whether a grant lets its holder invoke `cmd` with `args`: its command
covers it and its policy holds. With `opaque`, the invocation's body could
not be read here: a policy that reads `.body` and finds no data is left to
those who can read it, and counts as holding.

## Parameters

| Parameter | Type | Default value |
| ------ | ------ | ------ |
| `grant` | [`SpaceGrant`](https://minca.dev/api/core/interfaces/SpaceGrant.md) | `undefined` |
| `cmd` | `string` | `undefined` |
| `args` | `unknown` | `undefined` |
| `opaque?` | `boolean` | `false` |

## Returns

`boolean`
