Struct flechasdb_s3::syncfs::S3HashedFileOut

pub struct S3HashedFileOut { /* private fields */ }

Writable file (object) in an S3 bucket.

The object key will be the base path plus the URL-safe Base64 encoded SHA-256 hash.

SHA-256 checksum will also be enabled for the object.

Trait Implementations

impl HashedFileOut for S3HashedFileOut

fn persist(self, extension: impl AsRef<str>) -> Result<String, Error>

Uploads the contents to the S3 bucket.

Blocks until the upload completes. This function must be called within the context of a Tokio runtime, otherwise fails with Error::InvalidContext.

impl Write for S3HashedFileOut

fn write(&mut self, buf: &[u8]) -> Result<usize>

Write a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, fmt: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Selfwhere Self: Sized,

Creates a “by reference” adapter for this instance of Write.
