Enum TransactionIsolation 

pub enum TransactionIsolation {
    ReadCommitted,
    RepeatableRead,
    Serializable,
}

Transaction isolation level requested by a procedure via @isolation(...). Mirrors the PostgreSQL spec: lower variants tolerate more anomalies, higher ones cost more under contention. Banks running multi-row updates (transfers, postings) typically pick Serializable and pair it with retry-on-serialization-failure.

Variants

ReadCommitted

RepeatableRead

Serializable

Implementations

impl TransactionIsolation

pub fn parse(value: &str) -> Result<Self, CoolError>

pub const fn as_sql(&self) -> &'static str

Trait Implementations

impl Clone for TransactionIsolation

fn clone(&self) -> TransactionIsolation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransactionIsolation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TransactionIsolation

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TransactionIsolation

fn eq(&self, other: &TransactionIsolation) -> 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 TransactionIsolation

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for TransactionIsolation

impl Eq for TransactionIsolation

impl StructuralPartialEq for TransactionIsolation
