### Type Aliases

#### ArgsType

Ƭ **ArgsType**<`T`>: `T` extends (...`args`: infer A) => `unknown` ? `A` : `never`

Less strict version of Parameters

**Type parameters**

| Name |
| ---- |
| `T`  |

**Defined in**

[types/utils/index.ts:26](https://github.com/PolymathNetwork/polymesh-sdk/blob/31dfa0dc/src/types/utils/index.ts#L26)

***

#### Ensured

Ƭ **Ensured**<`T`, `K`>: `Required`<`Pick`<`T`, `K`>>

Pick a single property from T and ensure it is defined

**Type parameters**

| Name | Type              |
| ---- | ----------------- |
| `T`  | `T`               |
| `K`  | extends keyof `T` |

**Defined in**

[types/utils/index.ts:74](https://github.com/PolymathNetwork/polymesh-sdk/blob/31dfa0dc/src/types/utils/index.ts#L74)

***

#### HumanReadableType

Ƭ **HumanReadableType**<`T`>: `T` extends [`Entity`](https://developers.polymath.network/polymesh-sdk-api-reference/docs-alpha/classes/api_entities_entity.entity)<`unknown`, infer H> ? [`HumanReadableType`](#humanreadabletype)<`H`> : `T` extends `BigNumber` ? `string` : `T` extends `Date` ? `string` : `T` extends `object` ? { \[K in keyof T]: T\[K] extends Entity\<unknown, infer E> ? HumanReadableType\<E> : HumanReadableType\<T\[K]> } : `T`

Recursively traverse a type and transform its Entity properties into their human readable version (as if `.toHuman` had been called on all of them)

**Type parameters**

| Name |
| ---- |
| `T`  |

**Defined in**

[types/utils/index.ts:32](https://github.com/PolymathNetwork/polymesh-sdk/blob/31dfa0dc/src/types/utils/index.ts#L32)

***

#### Modify

Ƭ **Modify**<`T`, `R`>: `Omit`<`T`, keyof `R`> & `R`

Override T with the properties of R

**Type parameters**

| Name |
| ---- |
| `T`  |
| `R`  |

**Defined in**

[types/utils/index.ts:63](https://github.com/PolymathNetwork/polymesh-sdk/blob/31dfa0dc/src/types/utils/index.ts#L63)

***

#### Mutable

Ƭ **Mutable**<`Immutable`>: { -readonly \[K in keyof Immutable]: Immutable\[K] }

**Type parameters**

| Name        |
| ----------- |
| `Immutable` |

**Defined in**

[types/utils/index.ts:7](https://github.com/PolymathNetwork/polymesh-sdk/blob/31dfa0dc/src/types/utils/index.ts#L7)

***

#### WithRequired

Ƭ **WithRequired**<`T`, `K`>: `T` & { \[P in K]-?: T\[P] }

Ensure a specific property of T is defined

**Type parameters**

| Name | Type              |
| ---- | ----------------- |
| `T`  | `T`               |
| `K`  | extends keyof `T` |

**Defined in**

[types/utils/index.ts:69](https://github.com/PolymathNetwork/polymesh-sdk/blob/31dfa0dc/src/types/utils/index.ts#L69)
