Enum VersioningState 

pub enum VersioningState {
    Enabled,
    Suspended,
    Unversioned,
}

Per-bucket versioning state。AWS S3 では Enabled / Suspended の二択 (作成直後の bucket は status 未設定 = Unversioned 相当) なので、3 値に分けて 管理する。

Variants

Enabled

PUT は新 version_id を採番、DELETE は delete marker を追加。

Suspended

PUT は version_id = "null" で既存 null version を overwrite、 DELETE は null delete marker を追加 (chain 中の他 version は残る)。

Unversioned

旧来の non-versioned 動作 (S4 が version index を持たない bucket。 get_bucket_versioning は None 相当を返す)。

Implementations

impl VersioningState

pub fn as_aws_status(self) -> Option<&'static str>

AWS wire format ("Enabled" / "Suspended" / "") との往復用。

Trait Implementations

impl Clone for VersioningState

fn clone(&self) -> VersioningState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VersioningState

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VersioningState

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for VersioningState

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

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 VersioningState
