Storage functions¶
CandidacyBond¶
Fixed amount to deposit to become a collator.
When a collator calls leave_intent
they immediately receive the deposit back.
Python¶
result = substrate.query(
'CollatorSelection', 'CandidacyBond', []
)
Return value¶
'u128'
Candidates¶
The (community, limited) collation candidates.
Python¶
result = substrate.query(
'CollatorSelection', 'Candidates', []
)
Return value¶
[{'deposit': 'u128', 'who': 'AccountId'}]
DesiredCandidates¶
Desired number of candidates.
This should ideally always be less than [Config::MaxCandidates
] for weights to be correct.
Python¶
result = substrate.query(
'CollatorSelection', 'DesiredCandidates', []
)
Return value¶
'u32'
Invulnerables¶
The invulnerable, fixed collators.
Python¶
result = substrate.query(
'CollatorSelection', 'Invulnerables', []
)
Return value¶
['AccountId']
LastAuthoredBlock¶
Last block authored by collator.
Python¶
result = substrate.query(
'CollatorSelection', 'LastAuthoredBlock', ['AccountId']
)
Return value¶
'u32'
SlashDestination¶
Destination account for slashed amount.
Python¶
result = substrate.query(
'CollatorSelection', 'SlashDestination', []
)
Return value¶
'AccountId'
Errors¶
AlreadyCandidate¶
User is already a candidate
AlreadyInvulnerable¶
User is already an Invulnerable
NoAssociatedValidatorId¶
Account has no associated validator ID
NotAllowedCandidate¶
Account is now allowed to be a candidate due to an external reason (e.g. it might be participating in dApp staking)
NotCandidate¶
User is not a candidate
Permission¶
Permission issue
TooFewCandidates¶
Too few candidates
TooManyCandidates¶
Too many candidates
Unknown¶
Unknown error
ValidatorNotRegistered¶
Validator ID is not yet registered
