pub enum Result {
Error(Status),
Response(Any),
}
Expand description
The operation result, which can be either an error
or a valid response
.
If done
== false
, neither error
nor response
is set.
If done
== true
, exactly one of error
or response
can be set.
Some services might not provide the result.
Variants§
Error(Status)
The error result of the operation in case of failure or cancellation.
Response(Any)
The normal, successful response of the operation. If the original
method returns no data on success, such as Delete
, the response is
google.protobuf.Empty
. If the original method is standard
Get
/Create
/Update
, the response should be the resource. For other
methods, the response should have the type XxxResponse
, where Xxx
is the original method name. For example, if the original method name
is TakeSnapshot()
, the inferred response type is
TakeSnapshotResponse
.
Implementations§
Source§impl Result
impl Result
Sourcepub fn merge<B>(
field: &mut Option<Result>,
tag: u32,
wire_type: WireType,
buf: &mut B,
ctx: DecodeContext,
) -> Result<(), DecodeError>where
B: Buf,
pub fn merge<B>(
field: &mut Option<Result>,
tag: u32,
wire_type: WireType,
buf: &mut B,
ctx: DecodeContext,
) -> Result<(), DecodeError>where
B: Buf,
Decodes an instance of the message from a buffer, and merges it into self.
Sourcepub fn encoded_len(&self) -> usize
pub fn encoded_len(&self) -> usize
Returns the encoded length of the message without a length delimiter.
