Fields

mint_authority: COption<Pubkey>

[−] Expand description

Optional authority used to mint new tokens. The mint authority may only be provided during mint creation. If no mint authority is present then the mint has a fixed supply and no further tokens may be minted.

supply: u64

[−] Expand description

Total supply of tokens.

decimals: u8

[−] Expand description

Number of base 10 digits to the right of the decimal place.

is_initialized: bool

[−] Expand description

Is true if this structure has been initialized

freeze_authority: COption<Pubkey>

[−] Expand description

Optional authority to freeze token accounts.
