UpgradeCommitteeMembership¶
Calls¶
abdicate_membership¶
Allows the calling member to unilaterally quit without this being subject to a GC vote.
# Arguments
* origin
- Member of committee who wants to quit.
# Error
- Only primary key can abdicate.
- Last member of a group cannot abdicate.
Attributes¶
No attributes
Python¶
call = substrate.compose_call(
'UpgradeCommitteeMembership', 'abdicate_membership', {}
)
add_member¶
Adds a member who
to the group. May only be called from AddOrigin
or root.
# Arguments
* origin
- Origin representing AddOrigin
or root
* who
- IdentityId to be added to the group.
Attributes¶
Name | Type |
---|---|
who | IdentityId |
Python¶
call = substrate.compose_call(
'UpgradeCommitteeMembership', 'add_member', {'who': '[u8; 32]'}
)
disable_member¶
Disables a member at specific moment.
Please note that if member is already revoked (a "valid member"), its revocation time-stamp will be updated.
Any disabled member should NOT allow to act like an active member of the group. For
instance, a disabled CDD member should NOT be able to generate a CDD claim. However any
generated claim issued before at
would be considered as a valid one.
If you want to invalidate any generated claim, you should use Self::remove_member
.
# Arguments
* at
- Revocation time-stamp.
* who
- Target member of the group.
* expiry
- Time-stamp when who
is removed from CDD. As soon as it is expired, the
generated claims will be "invalid" as who
is not considered a member of the group.
Attributes¶
Name | Type |
---|---|
who | IdentityId |
expiry | Option<T::Moment> |
at | Option<T::Moment> |
Python¶
call = substrate.compose_call(
'UpgradeCommitteeMembership', 'disable_member', {
'at': (None, 'u64'),
'expiry': (None, 'u64'),
'who': '[u8; 32]',
}
)
remove_member¶
Removes a member who
from the set. May only be called from RemoveOrigin
or root.
Any claim previously generated by this member is not valid as a group claim. For
instance, if a CDD member group generated a claim for a target identity and then it is
removed, that claim will be invalid. In case you want to keep the validity of generated
claims, you have to use Self::disable_member
function
# Arguments
* origin
- Origin representing RemoveOrigin
or root
* who
- IdentityId to be removed from the group.
Attributes¶
Name | Type |
---|---|
who | IdentityId |
Python¶
call = substrate.compose_call(
'UpgradeCommitteeMembership', 'remove_member', {'who': '[u8; 32]'}
)
reset_members¶
Changes the membership to a new set, disregarding the existing membership.
May only be called from ResetOrigin
or root.
# Arguments
* origin
- Origin representing ResetOrigin
or root
* members
- New set of identities
Attributes¶
Name | Type |
---|---|
members | Vec<IdentityId> |
Python¶
call = substrate.compose_call(
'UpgradeCommitteeMembership', 'reset_members', {'members': ['[u8; 32]']}
)
set_active_members_limit¶
Change this group's limit for how many concurrent active members they may be.
# Arguments
* limit
- the number of active members there may be concurrently.
Attributes¶
Name | Type |
---|---|
limit | MemberCount |
Python¶
call = substrate.compose_call(
'UpgradeCommitteeMembership', 'set_active_members_limit', {'limit': 'u32'}
)
swap_member¶
Swaps out one member remove
for another member add
.
May only be called from SwapOrigin
or root.
# Arguments
* origin
- Origin representing SwapOrigin
or root
* remove
- IdentityId to be removed from the group.
* add
- IdentityId to be added in place of remove
.
Attributes¶
Name | Type |
---|---|
remove | IdentityId |
add | IdentityId |

call = substrate.compose_call(
'UpgradeCommitteeMembership', 'swap_member', {
'add': '[u8; 32]',
'remove': '[u8; 32]',
}
)
