Data is copied to Cloud Firestore and then verified to match the data in Cloud Datastore.

pub const REDIRECT_EVENTUALLY_CONSISTENT_READS: MigrationStep

Eventually-consistent reads are redirected to Cloud Firestore.

pub const REDIRECT_STRONGLY_CONSISTENT_READS: MigrationStep

Strongly-consistent reads are redirected to Cloud Firestore.

pub const REDIRECT_WRITES: MigrationStep

Writes are redirected to Cloud Firestore.

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 MigrationStep

fn clone(&self) -> MigrationStep

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MigrationStep

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

Formats the value using the given formatter.

impl Default for MigrationStep

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MigrationStep

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 MigrationStep

fn from(value: i32) -> Self

Converts to this type from the input type.

impl PartialEq for MigrationStep

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
