ERC1155

Inherits: IERC1155

Title: ERC1155

Author: Modified from OpenZeppelin (https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC1155/ERC1155.sol)

Stateless Diamond facet for the ERC-1155 Multi-Token Standard.

All logic lives in ERC1155Lib. This contract is a pure delegator. safeTransferFrom/safeBatchTransferFrom are the movement selectors a movement-replacing extension replaces; only one such extension per diamond (D25, #234).

lattice-version: 0.1.0

isApprovedForAll

Returns true if operator is approved to transfer account's tokens.

function isApprovedForAll(address account, address operator) public view virtual returns (bool);

setApprovalForAll

Grants or revokes permission to operator to transfer the caller's tokens.

function safeTransferFrom(address from, address to, uint256 id, uint256 value, bytes calldata data) public virtual;

Parameters

Name	Type	Description
from	`address`
to	`address`
id	`uint256`
value	`uint256`
data	`bytes`

safeBatchTransferFrom

Batched version of safeTransferFrom.

function safeBatchTransferFrom(
        address from,
        address to,
        uint256[] calldata ids,
        uint256[] calldata values,

    ) public virtual;

Parameters

Name	Type	Description

exportSelectors

ERC-8153 selector export: this facet's cuttable selectors, tightly packed (4 bytes each).

Excludes exportSelectors() itself (0x0ef22643) - it is never cut into a diamond. Order matches forge inspect ERC1155 methodIdentifiers (alphabetical by signature); kept in exact parity by ExportSelectorsParityTest.

function exportSelectors() external pure virtual returns (bytes memory selectors);

Returns
