Implementations

impl ConcurrencyMode

pub const CONCURRENCY_MODE_UNSPECIFIED: ConcurrencyMode

Unspecified.

pub const PESSIMISTIC: ConcurrencyMode

Pessimistic concurrency.

pub const OPTIMISTIC: ConcurrencyMode

Optimistic concurrency.

pub const OPTIMISTIC_WITH_ENTITY_GROUPS: ConcurrencyMode

Optimistic concurrency with entity groups.

pub fn value(&self) -> i32

Gets the enum value.

pub fn as_str_name(&self) -> Cow<'static, str>

Gets the enum value as a string.

pub fn from_str_name(name: &str) -> Option<Self>

Creates an enum value from the value name.

Trait Implementations

impl Clone for ConcurrencyMode

fn clone(&self) -> ConcurrencyMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConcurrencyMode

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

Formats the value using the given formatter.

impl Default for ConcurrencyMode

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ConcurrencyMode

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<i32> for ConcurrencyMode

fn from(value: i32) -> Self

Converts to this type from the input type.

impl PartialEq for ConcurrencyMode

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
