impl TransactionApi

Source

pub fn proxy( &self, real: Real, force_proxy_type: ForceProxyType, call: Call, ) -> StaticPayload<Proxy>

Dispatch the given call from an account that the sender is authorised for through add_proxy.

The dispatch origin for this call must be Signed.

Parameters:

  • real: The account that the proxy will make a call on behalf of.
  • force_proxy_type: Specify the exact proxy type to be used and checked for this call.
  • call: The call to be made by the real account.
Source

pub fn add_proxy( &self, delegate: Delegate, proxy_type: ProxyType, delay: Delay, ) -> StaticPayload<AddProxy>

Register a proxy account for the sender that is able to make calls on its behalf.

The dispatch origin for this call must be Signed.

Parameters:

  • proxy: The account that the caller would like to make a proxy.
  • proxy_type: The permissions allowed for this proxy account.
  • delay: The announcement period required of the initial proxy. Will generally be zero.
Source

pub fn remove_proxy( &self, delegate: Delegate, proxy_type: ProxyType, delay: Delay, ) -> StaticPayload<RemoveProxy>

Unregister a proxy account for the sender.

The dispatch origin for this call must be Signed.

Parameters:

  • proxy: The account that the caller would like to remove as a proxy.
  • proxy_type: The permissions currently enabled for the removed proxy account.
Source

pub fn remove_proxies(&self) -> StaticPayload<RemoveProxies>

Unregister all proxy accounts for the sender.

The dispatch origin for this call must be Signed.

WARNING: This may be called on accounts created by pure, however if done, then the unreserved fees will be inaccessible. All access to this account will be lost.

Source

pub fn create_pure( &self, proxy_type: ProxyType, delay: Delay, index: Index, ) -> StaticPayload<CreatePure>

Spawn a fresh new account that is guaranteed to be otherwise inaccessible, and initialize it with a proxy of proxy_type for origin sender.

Requires a Signed origin.

  • proxy_type: The type of the proxy that the sender will be registered as over the new account. This will almost always be the most permissive ProxyType possible to allow for maximum flexibility.
  • index: A disambiguation index, in case this is called multiple times in the same transaction (e.g. with utility::batch). Unless you’re using batch you probably just want to use 0.
  • delay: The announcement period required of the initial proxy. Will generally be zero.

Fails with Duplicate if this has already been called in this transaction, from the same sender, with the same parameters.

Fails if there are insufficient funds to pay for deposit.

Source

pub fn kill_pure( &self, spawner: Spawner, proxy_type: ProxyType, index: Index, height: Height, ext_index: ExtIndex, ) -> StaticPayload<KillPure>

Removes a previously spawned pure proxy.

WARNING: All access to this account will be lost. Any funds held in it will be inaccessible.

Requires a Signed origin, and the sender account must have been created by a call to pure with corresponding parameters.

  • spawner: The account that originally called pure to create this account.
  • index: The disambiguation index originally passed to pure. Probably 0.
  • proxy_type: The proxy type originally passed to pure.
  • height: The height of the chain when the call to pure was processed.
  • ext_index: The extrinsic index in which the call to pure was processed.

Fails with NoPermission in case the caller is not a previously created pure account whose pure call has corresponding parameters.

Source

pub fn announce( &self, real: Real, call_hash: CallHash, ) -> StaticPayload<Announce>

Publish the hash of a proxy-call that will be made in the future.

This must be called some number of blocks before the corresponding proxy is attempted if the delay associated with the proxy relationship is greater than zero.

No more than MaxPending announcements may be made at any one time.

This will take a deposit of AnnouncementDepositFactor as well as AnnouncementDepositBase if there are no other pending announcements.

The dispatch origin for this call must be Signed and a proxy of real.

Parameters:

  • real: The account that the proxy will make a call on behalf of.
  • call_hash: The hash of the call to be made by the real account.
Source

pub fn remove_announcement( &self, real: Real, call_hash: CallHash, ) -> StaticPayload<RemoveAnnouncement>

Remove a given announcement.

May be called by a proxy account to remove a call they previously announced and return the deposit.

The dispatch origin for this call must be Signed.

Parameters:

  • real: The account that the proxy will make a call on behalf of.
  • call_hash: The hash of the call to be made by the real account.
Source

pub fn reject_announcement( &self, delegate: Delegate, call_hash: CallHash, ) -> StaticPayload<RejectAnnouncement>

Remove the given announcement of a delegate.

May be called by a target (proxied) account to remove a call that one of their delegates (delegate) has announced they want to execute. The deposit is returned.

The dispatch origin for this call must be Signed.

Parameters:

  • delegate: The account that previously announced the call.
  • call_hash: The hash of the call to be made.
Source

pub fn proxy_announced( &self, delegate: Delegate, real: Real, force_proxy_type: ForceProxyType, call: Call, ) -> StaticPayload<ProxyAnnounced>

Dispatch the given call from an account that the sender is authorized for through add_proxy.

Removes any corresponding announcement(s).

The dispatch origin for this call must be Signed.

Parameters:

  • real: The account that the proxy will make a call on behalf of.
  • force_proxy_type: Specify the exact proxy type to be used and checked for this call.
  • call: The call to be made by the real account.
