Struct spl_token::state::Mint

#[repr(C)]
pub struct Mint {
    pub mint_authority: COption<Pubkey>,
    pub supply: u64,

    pub is_initialized: bool,

}

Mint data.

Fields

mint_authority: COption<Pubkey>

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

Total supply of tokens.

decimals: u8

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

is_initialized: bool

Is true if this structure has been initialized

freeze_authority: COption<Pubkey>

Optional authority to freeze token accounts.
