Struct S3RangeReader 

pub struct S3RangeReader { /* private fields */ }

S3-backed implementation of RangeReader.

Reads byte ranges from objects in S3 or S3-compatible storage (MinIO, GCS, etc.) using HTTP range requests. The object size is fetched once on creation via HEAD.

Implementations

impl S3RangeReader

pub async fn new( client: Client, bucket: String, key: String, ) -> Result<Self, IoError>

Create a new S3RangeReader for the given bucket and key.

This performs a HEAD request to determine the object size. Returns an error if the object does not exist or is inaccessible.

pub fn bucket(&self) -> &str

Get the bucket name.

pub fn key(&self) -> &str

Get the object key.

Trait Implementations

impl Clone for S3RangeReader

fn clone(&self) -> S3RangeReader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl RangeReader for S3RangeReader

fn read_exact_at<'life0, 'async_trait>( &'life0 self, offset: u64, len: usize, ) -> Pin<Box<dyn Future<Output = Result<Bytes, IoError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Read exactly len bytes starting at offset.

fn size(&self) -> u64

Get the total size of the resource in bytes.

fn identifier(&self) -> &str

Get a unique identifier for this resource (for logging and cache keys).
