Struct S3Storage 

pub struct S3Storage { /* private fields */ }

S3-compatible object storage backend.

Implementations

impl S3Storage

pub fn new( bucket: String, region: String, endpoint: Option<String>, ) -> Result<S3Storage, StoreError>

Create a new S3 storage backend.

Uses AWS default credential chain (IRSA, env vars, instance profile). Set endpoint for non-AWS S3-compatible services (MinIO, RustFS, R2).

pub fn bucket(&self) -> &str

Return the bucket name.

pub fn region(&self) -> &str

Return the region.

pub fn endpoint(&self) -> Option<&str>

Return the custom endpoint, if any.
