Struct S3ServiceState 

pub struct S3ServiceState { /* private fields */ }

Top-level S3 service state holding all buckets.

Bucket names are globally unique across accounts, enforced by global_bucket_owner. Per-account bucket data is stored in buckets.

All fields are accessed concurrently via DashMap; no external locking is required.

Implementations

impl S3ServiceState

pub fn new() -> Self

Create a new, empty service state.

pub fn create_bucket( &self, name: String, region: String, owner: Owner, ) -> Result<(), S3ServiceError>

Create a new bucket.

Errors

• S3ServiceError::BucketAlreadyOwnedByYou if the caller already owns a bucket with the same name.
• S3ServiceError::BucketAlreadyExists if the bucket name is taken by a different account.

pub fn delete_bucket(&self, name: &str) -> Result<(), S3ServiceError>

Delete a bucket.

Errors

• S3ServiceError::NoSuchBucket if the bucket does not exist.
• S3ServiceError::BucketNotEmpty if the bucket still contains objects or in-progress multipart uploads.

pub fn get_bucket( &self, name: &str, ) -> Result<Ref<'_, String, S3Bucket>, S3ServiceError>

Get an immutable reference to a bucket.

Errors

Returns S3ServiceError::NoSuchBucket if the bucket does not exist.

pub fn get_bucket_mut( &self, name: &str, ) -> Result<RefMut<'_, String, S3Bucket>, S3ServiceError>

Get a mutable reference to a bucket.

Errors

Returns S3ServiceError::NoSuchBucket if the bucket does not exist.

pub fn list_buckets(&self) -> Vec<(String, DateTime<Utc>)>

List all buckets, returning (name, creation_date) pairs sorted by name.

pub fn bucket_exists(&self, name: &str) -> bool

Check whether a bucket exists.

pub fn reset(&self)

Reset all state, removing all buckets.
