FulfillmentContextLibrary

Library for packing, unpacking, and storing FulfillmentContext structs

Uses bit manipulation to pack all fields into a single uint256 for transient storage

State Variables

uint256 private constant VALID_MASK = 1 << 127;

uint256 private constant PRICE_MASK = (1 << 96) - 1;

Packs the struct into a single 256-bit slots and sets the validation bit.

function pack(FulfillmentContext memory x) internal pure returns (uint256);

Parameters

Name	Type	Description
`x`	`FulfillmentContext`	The FulfillmentContext struct to pack

Returns

Name	Type	Description
`<none>`	`uint256`	Packed uint256 containing valid bit and price

Unpacks the struct from a single uint256

function unpack(uint256 packed) internal pure returns (FulfillmentContext memory);

Parameters

Name	Type	Description
`packed`	`uint256`	Packed uint256 containing the valid bit and price

Returns

Name	Type	Description
`<none>`	`FulfillmentContext`	The unpacked FulfillmentContext struct

Packs and stores the object to transient storage

function store(FulfillmentContext memory x, bytes32 requestDigest) internal;

Parameters

Name	Type	Description
`x`	`FulfillmentContext`	The FulfillmentContext struct to store
`requestDigest`	`bytes32`	The storage key for the transient storage

Loads from transient storage and unpacks to FulfillmentContext

function load(bytes32 requestDigest) internal view returns (FulfillmentContext memory);

Parameters

Name	Type	Description
`requestDigest`	`bytes32`	The storage key to load from

Returns

Name	Type	Description
`<none>`	`FulfillmentContext`	The loaded and unpacked FulfillmentContext struct
