Struct OptionTerms 

Source 
pub struct OptionTerms {
    pub creator_puzzle_hash: Bytes32,
    pub owner_puzzle_hash: Bytes32,
    pub underlying_amount: u64,
    pub strike_type: OptionType,
    pub expiry_seconds: u64,
}
Expand description

The terms of a covered option: who created it, who owns (may exercise) it, how much XCH it locks as the underlying, what strike the holder must pay, and when it expires.

Key-free: the parties are named by their Bytes32 puzzle hashes, never by keys. The underlying is XCH (v0.1.0 scope); strike_type may be any OptionType (it is curried into the option puzzle), though only an XCH strike can be exercised in v0.1.0 (see crate::exercise).

Fields§

§creator_puzzle_hash: Bytes32

The puzzle hash the creator reclaims the underlying to on clawback (after expiry).

§owner_puzzle_hash: Bytes32

The puzzle hash the option singleton is minted to — its initial holder/owner.

§underlying_amount: u64

The amount of XCH (in mojos) locked as the underlying.

§strike_type: OptionType

The asset + amount the holder must pay to exercise the option.

§expiry_seconds: u64

The absolute unix timestamp (seconds) at which the option expires: exercise is valid strictly before it, clawback strictly after it.

Implementations§

Source§

impl OptionTerms

Source

pub fn new( creator_puzzle_hash: Bytes32, underlying_amount: u64, strike_type: OptionType, expiry_seconds: u64, ) -> Self

Terms with the creator as the initial owner (the common self-minted case).

The option is minted to creator_puzzle_hash and, on clawback, reclaimed to it. Use the struct literal directly to mint an option owned by a different party.
