Module object_store 

Cloud object storage abstractions: URL parsing, byte-range requests, credentials, presigned URLs, multipart upload, and range coalescing.

Structs

ByteRangeRequest

A request for a specific byte range of a cloud object.

CloudRangeCoalescer

Merges nearby byte-range requests into larger ones to reduce round-trip overhead when reading from cloud object storage.

CompletedPart

Tracks the state of an S3 multipart upload.

MultipartUploadState

State machine for an in-progress multipart upload.

ObjectMetadata

Metadata for a cloud object.

ObjectUrl

A parsed cloud object URL.

PresignedUrlConfig

Configuration for presigned URL generation.

PresignedUrlGenerator

Generates presigned URLs using AWS SigV4 / GCS v4 signing.

Enums

CloudCredentials

Authentication credentials for cloud object storage.

CloudError

Errors produced by the cloud I/O layer.

CloudScheme

Supported cloud URL schemes.

HttpMethod

HTTP verb used in a presigned URL.

Functions

hex_encode

Encode a byte slice as a lowercase hexadecimal string.

hmac_sha256

Compute HMAC-SHA256.

hmac_sha256_hex

Compute HMAC-SHA256 and return the result as a lowercase hex string.

sha256
