Expand description

An account that has staked tokens into a Quarry.

Fields

quarry: Pubkey

Key of the Quarry this Miner works on.

authority: Pubkey

Authority who manages this Miner. All withdrawals of tokens must accrue to TokenAccounts owned by this account.

bump: u8

Bump.

token_vault_key: Pubkey

TokenAccount to hold the Miner’s staked LP tokens.

rewards_earned: u64

Stores the amount of tokens that the Miner may claim. Whenever the Miner claims tokens, this is reset to 0.

rewards_per_token_paid: u128

A checkpoint of the Quarry’s reward tokens paid per staked token.

When the Miner is initialized, this number starts at 0. On the first quarry_mine::stake_tokens, the Quarry#update_rewards_and_miner method is called, which updates this checkpoint to the current quarry value.

On a quarry_mine::claim_rewards, the difference in checkpoints is used to calculate the amount of tokens owed.

balance: u64

Number of tokens the Miner holds.

index: u64

Index of the Miner.

Implementations

Trait Implementations

Deserializes previously initialized account data. Should fail for all uninitialized accounts, where the bytes are zeroed. Implementations should be unique to a particular account type so that one can never successfully deserialize the data of one account type into another. For example, if the SPL token program were to implement this trait, it should be impossible to deserialize a Mint account into a token Account. Read more

Deserializes account data without checking the account discriminator. This should only be used on account initialization, when the bytes of the account are zeroed. Read more

Serializes the account data into writer.

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes. Read more

Deserialize this instance from a slice of bytes.

Serialize this instance into a vector of bytes.

Returns a copy of the value. Read more

Performs copy-assignment from source. Read more

Formats the value using the given formatter. Read more

Returns the “default value” for a type. Read more
