Enum tea_sdk::actor_txns::context::ReadConflictMode

pub enum ReadConflictMode {
    CreditOk,
    DebitOk,
    BothOk,
    BothConflict,
}

ReadConflictMode is used to determine if other context have a Credit or Debit operation, will that cause this READ operation invalid. For example, if I read an account balance, and if it is greater than a certain amount then running my logic. In this case, if there is another concurrent credit operation, my logic is still valid. Because credit will just increase the account balance. my original logic “greater than” is still valid. But if there was a Debit operation, my logic might be “invalid” because the debit reduce the balance, that my “greater than” logic might be fail. In this case, the read is conflict. It may cause a rerun when merge Those four enum values means in what situation, my read will be valid / invalid These values are important when running a context merge or rebase

Trait Implementations

impl Clone for ReadConflictMode

fn clone(&self) -> ReadConflictMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ReadConflictMode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ReadConflictMode

fn deserialize<__D>( __deserializer: __D ) -> Result<ReadConflictMode, <__D as Deserializer<'de>>::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ReadConflictMode

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

This method tests for self and other values to be equal, and is used by ==.

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

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