Struct UserNonce

Source

pub struct UserNonce {
    pub discriminator: [u8; 8],
    pub nonce: u64,
}

Expand description

User nonce account - tracks user’s current nonce for mass cancellation

Layout:

[0..8] discriminator (8 bytes)
[8..16] nonce (8 bytes)

Fields§

§discriminator: [u8; 8]

Account discriminator

§nonce: u64

Current nonce value
