Struct ConfigBuilder 

pub struct ConfigBuilder<Isolation = ServerDefault, Access = ServerDefault> { /* private fields */ }

Builds a TransactionConfig, rejecting meaningless combinations at compile time.

Start with TransactionConfig::builder, pick an isolation level and an access mode in either order, then call build. The type parameters track the choices and are inferred.

Implementations

impl<Isolation, Access> ConfigBuilder<Isolation, Access>

pub const fn isolation_level( self, level: IsolationLevel, ) -> ConfigBuilder<Dynamic, Access>

Selects an isolation level supplied at runtime.

pub const fn read_uncommitted(self) -> ConfigBuilder<ReadUncommitted, Access>

Uses READ UNCOMMITTED isolation.

pub const fn read_committed(self) -> ConfigBuilder<ReadCommitted, Access>

Uses READ COMMITTED isolation.

pub const fn repeatable_read(self) -> ConfigBuilder<RepeatableRead, Access>

Uses REPEATABLE READ isolation.

pub const fn serializable(self) -> ConfigBuilder<Serializable, Access>

Uses SERIALIZABLE isolation.

pub const fn access_mode( self, mode: AccessMode, ) -> ConfigBuilder<Isolation, Dynamic>

Selects an access mode supplied at runtime.

pub const fn read_only(self) -> ConfigBuilder<Isolation, ReadOnly>

Rejects writes in the transaction.

pub const fn read_write(self) -> ConfigBuilder<Isolation, ReadWrite>

Permits reads and writes in the transaction.

pub const fn build(self) -> TransactionConfig

Returns the finished TransactionConfig.

impl ConfigBuilder<Serializable, ReadOnly>

pub const fn deferrable(self) -> Self

Adds DEFERRABLE: the transaction waits for a snapshot that cannot cause a serialization failure, then runs without that risk.

Only available after .serializable() and .read_only().
