Struct opendal :: operator_functions :: FunctionWriter Copy item path

impl FunctionWriter

pub fn append(self, v: 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, v: usize) -> Self

Set the chunk size of op.

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

§NOTE

Service could have their own limitation for chunk size. It’s possible that chunk size is not equal to the given chunk size.

For example:

AWS S3 requires the part size to be in [5MiB, 5GiB].
GCS requires the part size to be aligned with 256 KiB.

The services will alter the chunk size to meet their requirements.

pub fn buffer(self, v: usize) -> Self

👎Deprecated: Please use chunk instead

Set the chunk size of op.

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

Set the content type of option

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

Set the content disposition of option

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

Set the content type of option

pub fn call(self) -> Result<BlockingWriter>

Call the function to consume all the input and generate a result.
