Struct MatchIxOffsets

pub struct MatchIxOffsets;

Expand description

Match instruction data layout offsets (for cross-instruction references).

Layout for single maker (332 bytes):

[0]: discriminator (1 byte)
[1..33]: taker_hash (32 bytes) <- taker message
[33..98]: taker_compact (65 bytes) <- taker pubkey at offset 33+8=41
[98..162]: taker_signature (64 bytes) <- taker signature
[162]: num_makers (1 byte)
[163..195]: maker_hash (32 bytes) <- maker message
[195..260]: maker_compact (65 bytes) <- maker pubkey at offset 195+8=203
[260..324]: maker_signature (64 bytes) <- maker signature
[324..332]: maker_fill_amount (8 bytes)

Implementations§

impl MatchIxOffsets

pub const TAKER_MESSAGE: u16 = 1

Taker hash (message) starts at offset 1

pub const TAKER_PUBKEY: u16 = 41

Taker compact.maker (pubkey) at 33+8

pub const TAKER_SIGNATURE: u16 = 98

Taker signature at offset 98

pub const NUM_MAKERS: u16 = 162

num_makers at offset 162

pub fn maker_offsets(maker_index: usize) -> MakerOffsets

Calculate offsets for a maker order in the match instruction data. Each maker entry is: hash(32) + compact(65) + sig(64) + fill(8) = 169 bytes
