Resource GasService

struct GasService has store, key

Fields

id: object::UID

inner: versioned::Versioned

Constants

const VERSION: u64 = 0;

Function init

fun init(ctx: &mut tx_context::TxContext)

Implementation

fun init(ctx: &mut TxContext) {
    transfer::share_object(GasService {
        id: object::new(ctx),
        inner: versioned::create(
            VERSION,
            gas_service_v0::new(
                version_control(),
                ctx,
            ),
            ctx,
        ),
    });

    transfer::public_transfer(
        operator_cap::create(ctx),
        ctx.sender(),
    );

    transfer::public_transfer(
        owner_cap::create(ctx),
        ctx.sender(),
    );
}

Function allow_function

entry fun allow_function(self: &mut gas_service::GasService, _: &owner_cap::OwnerCap, version: u64, function_name: ascii::String)

Implementation

entry fun allow_function(self: &mut GasService, _: &OwnerCap, version: u64, function_name: String) {
    self.value_mut!(b"allow_function").allow_function(version, function_name);
}

Function disallow_function

entry fun disallow_function(self: &mut gas_service::GasService, _: &owner_cap::OwnerCap, version: u64, function_name: ascii::String)

Implementation

entry fun disallow_function(self: &mut GasService, _: &OwnerCap, version: u64, function_name: String) {
    self.value_mut!(b"disallow_function").disallow_function(version, function_name);
}

Function pay_gas

Pay gas for a contract call. This function is called by the channel that wants to pay gas for a contract call. It can also be called by the user to pay gas for a contract call, while setting the sender as the channel ID.

public fun pay_gas<T>(self: &mut gas_service::GasService, message_ticket: &message_ticket::MessageTicket, coin: coin::Coin<T>, refund_address: address, params: vector<u8>)

Implementation

public fun pay_gas<T>(
    self: &mut GasService,
    message_ticket: &MessageTicket,
    coin: Coin<T>,
    refund_address: address,
    params: vector<u8>,
) {
    self
        .value_mut!(b"pay_gas")
        .pay_gas<T>(
            message_ticket,
            coin,
            refund_address,
            params,
        );
}

Function add_gas

Add gas for an existing cross-chain contract call. This function can be called by a user who wants to add gas for a contract call with insufficient gas.

public fun add_gas<T>(self: &mut gas_service::GasService, coin: coin::Coin<T>, message_id: ascii::String, refund_address: address, params: vector<u8>)

Implementation

public fun add_gas<T>(self: &mut GasService, coin: Coin<T>, message_id: String, refund_address: address, params: vector<u8>) {
    self
        .value_mut!(b"add_gas")
        .add_gas<T>(
            coin,
            message_id,
            refund_address,
            params,
        );
}

Function collect_gas

public fun collect_gas<T>(self: &mut gas_service::GasService, _: &operator_cap::OperatorCap, receiver: address, amount: u64, ctx: &mut tx_context::TxContext)

Implementation

public fun collect_gas<T>(self: &mut GasService, _: &OperatorCap, receiver: address, amount: u64, ctx: &mut TxContext) {
    self
        .value_mut!(b"collect_gas")
        .collect_gas<T>(
            receiver,
            amount,
            ctx,
        )
}

Function refund

public fun refund<T>(self: &mut gas_service::GasService, _: &operator_cap::OperatorCap, message_id: ascii::String, receiver: address, amount: u64, ctx: &mut tx_context::TxContext)

Implementation

public fun refund<T>(self: &mut GasService, _: &OperatorCap, message_id: String, receiver: address, amount: u64, ctx: &mut TxContext) {
    self
        .value_mut!(b"refund")
        .refund<T>(
            message_id,
            receiver,
            amount,
            ctx,
        );
}

Function balance

public fun balance<T>(self: &gas_service::GasService): &balance::Balance<T>

Implementation
