A function to get all members of a role is not provided because that
would be unbounded. To enumerate all members of a role, use
[AccessControl::get_role_member_count()] to get the total number of
members and then use [AccessControl::get_role_member()] to retrieve
each member one by one.
e - Access to Soroban environment.role - The role to query.index - The index of the account to retrieve.AccessControlError::IndexOutOfBounds] - If the index is out of
bounds for the role's member list.fn get_role_member(

e - Access to Soroban environment.This function returns all roles that currently have at least one member.
The maximum number of roles is limited by [MAX_ROLES].
fn get_existing_roles(env: soroban_sdk::Env) -> soroban_sdk::VecInitiates the admin role transfer. Admin privileges for the current admin are not revoked until the recipient accepts the transfer. Overrides the previous pending transfer if there is one.
e - Access to Soroban environment.new_admin - The account to transfer the admin privileges to.live_until_ledger - The ledger number at which the pending transfer
expires. If live_until_ledger is 0, the pending transfer is
cancelled. live_until_ledger argument is implicitly bounded by the
maximum allowed TTL extension for a temporary storage entry and
specifying a higher value will cause the code to panic.crate::role_transfer::RoleTransferError::NoPendingTransfer] - If
trying to cancel a transfer that doesn't exist.crate::role_transfer::RoleTransferError::InvalidLiveUntilLedger] -
If the specified ledger is in the past.crate::role_transfer::RoleTransferError::InvalidPendingAccount] -
If the specified pending account is not the same as the provided new
address.fn transfer_admin_role(
