Struct opendal::raw::OpWrite

pub struct OpWrite { /* private fields */ }

Args for write operation.

Implementations

impl OpWrite

pub fn new() -> Self

Create a new OpWrite.

If input path is not a file path, an error will be returned.

pub fn append(&self) -> bool

Get the append from op.

The append is the flag to indicate that this write operation is an append operation.

pub fn with_append(self, append: bool) -> Self

Set the append mode of op.

If the append mode is set, the data will be appended to the end of the file.

Notes

Service could return Unsupported if the underlying storage does not support append.

pub fn chunk(&self) -> Option<usize>

Get the chunk from op.

The chunk is used by service to decide the chunk size of the underlying writer.

pub fn with_chunk(self, chunk: usize) -> Self

Set the chunk of op.

If chunk is set, the data will be chunked by the underlying writer.

NOTE

Service could have their own minimum chunk size while perform write operations like multipart uploads. So the chunk size may be larger than the given buffer size.

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

Get the content type from option

pub fn with_content_type(self, content_type: &str) -> Self

Set the content type of option

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

Get the content disposition from option

pub fn with_content_disposition(self, content_disposition: &str) -> Self

Set the content disposition of option

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

Get the cache control from option

pub fn with_cache_control(self, cache_control: &str) -> Self

Set the content type of option

pub fn concurrent(&self) -> usize

Get the concurrent.

pub fn with_concurrent(self, concurrent: usize) -> Self

Set the maximum concurrent write task amount.

Trait Implementations

impl Clone for OpWrite

fn clone(&self) -> OpWrite

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OpWrite

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for OpWrite

fn default() -> OpWrite

Returns the “default value” for a type.

impl From<OpWrite> for PresignOperation

fn from(v: OpWrite) -> Self

Converts to this type from the input type.
