Enum Data

pub enum Data {
    ChecksummedData(ChecksummedData),
    Reference(GetObjectMediaRequest),
}

A portion of the data for the object.

Variants

ChecksummedData(ChecksummedData)

The data to insert. If a crc32c checksum is provided that doesn’t match the checksum computed by the service, the request will fail.

Reference(GetObjectMediaRequest)

A reference to an existing object. This can be used to support several use cases:

• Writing a sequence of data buffers supports the basic use case of uploading a complete object, chunk by chunk.
• Writing a sequence of references to existing objects allows an object to be composed from a collection of objects, which can be used to support parallel object writes.
• Writing a single reference with a given offset and size can be used to create an object from a slice of an existing object.
• Writing an object referencing a object slice (created as noted above) followed by a data buffer followed by another object slice can be used to support delta upload functionality.

Implementations

impl Data

pub fn encode<B>(&self, buf: &mut B)

where B: BufMut,

pub fn merge<B>( field: &mut Option<Data>, tag: u32, wire_type: WireType, buf: &mut B, ctx: DecodeContext, ) -> Result<(), DecodeError>

where B: Buf,

pub fn encoded_len(&self) -> usize

Trait Implementations

impl Clone for Data

fn clone(&self) -> Data

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Data

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

Formats the value using the given formatter.

impl PartialEq for Data

fn eq(&self, other: &Data) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
