Enum TransactionMode 

pub enum TransactionMode {
    IsolationLevel {
        level: IsolationLevel,
        meta: Meta,
    },
    AccessMode {
        access: TransactionAccessMode,
        meta: Meta,
    },
    Deferrable {
        deferrable: bool,
        meta: Meta,
    },
    ConsistentSnapshot {
        meta: Meta,
    },
}

One transaction mode in a START TRANSACTION / SET TRANSACTION mode list (and in the session SET SESSION CHARACTERISTICS).

Variants

IsolationLevel

ISOLATION LEVEL <level> — set the transaction’s isolation level.

Fields

level: IsolationLevel

Which isolation level; see IsolationLevel.

meta: Meta

Source location and node identity.

AccessMode

READ ONLY / READ WRITE — set the transaction’s access mode.

Fields

access: TransactionAccessMode

Which access mode; see TransactionAccessMode.

meta: Meta

Source location and node identity.

Deferrable

DEFERRABLE / NOT DEFERRABLE: the two spellings are one mode toggled by a flag; deferrable is false only for the NOT spelling.

Fields

deferrable: bool

Whether the deferrable form was present in the source.

meta: Meta

Source location and node identity.

ConsistentSnapshot

WITH CONSISTENT SNAPSHOT: establish a consistent read view when the transaction starts (MySQL).

Fields

meta: Meta

Source location and node identity.

Trait Implementations

impl Clone for TransactionMode

fn clone(&self) -> TransactionMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransactionMode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TransactionMode

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for TransactionMode

impl Hash for TransactionMode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)
