Enum StorageClass 

pub enum StorageClass {
    Standard,
    ExpressOneZone,
    IntelligentTiering,
    GlacierInstantRetrieval,
}

S3-compatible storage class for checkpoint objects.

Maps to the x-amz-storage-class header on PUT requests. Provider-specific strings are used because each cloud provider has different class names.

Variants

Standard

S3 Standard (default). Multi-AZ durability, low latency.

ExpressOneZone

S3 Express One Zone. Single-digit ms latency, -55% PUT / -85% GET cost.

IntelligentTiering

S3 Intelligent-Tiering. Automatic cost optimization by access pattern.

GlacierInstantRetrieval

S3 Glacier Instant Retrieval. Archive with millisecond access, -68% cost.

Implementations

impl StorageClass

pub fn as_s3_str(self) -> &'static str

S3 storage class header value.

pub fn from_config(s: &str) -> Option<Self>

Parse from a configuration string (case-insensitive, underscores/hyphens tolerated).

Trait Implementations

impl Clone for StorageClass

fn clone(&self) -> StorageClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StorageClass

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

Formats the value using the given formatter.

impl Display for StorageClass

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

Formats the value using the given formatter.

impl Hash for StorageClass

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for StorageClass

fn eq(&self, other: &StorageClass) -> 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.
