Struct AccountConstraints 

pub struct AccountConstraints {
    pub key: Pubkey,
    pub program_id: Pubkey,
    pub data_hash: Hash,
}

The account constraints a Condition would wait on. Note: ideally this would be function that accepts an Account and returns a bool, but we don’t have a way to pass functions over the wire. To simulate higher order programming, create your own program that includes an instruction that sets account data to a boolean. Pass that account key and program_id here.

Fields

key: Pubkey

The account holder.

program_id: Pubkey

The program id that must own the account at key.

data_hash: Hash

The hash of the data in the account at key.

Trait Implementations

impl Clone for AccountConstraints

fn clone(&self) -> AccountConstraints

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AccountConstraints

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AccountConstraints

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AccountConstraints

fn eq(&self, other: &AccountConstraints) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for AccountConstraints

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for AccountConstraints
