"""#### Introduction
The Byte Stream API enables a client to read and write a stream of bytes to
and from a resource. Resources have names, and these names are supplied in
the API calls below to identify the resource that is being read from or
written to.
All implementations of the Byte Stream API export the interface defined here:
* `Read()`: Reads the contents of a resource.
* `Write()`: Writes the contents of a resource. The client can call `Write()`
multiple times with the same resource and can check the status of the write
by calling `QueryWriteStatus()`.
#### Service parameters and metadata
The ByteStream API provides no direct way to access/modify any metadata
associated with the resource.
#### Errors
The errors returned by the service are in the Google canonical error space.

"""`Write()` is used to send the contents of a resource as a sequence of

A `Write()` action is resumable. If there is an error or the connection is
broken during the `Write()`, the client should check the status of the
`Write()` by calling `QueryWriteStatus()` and continue writing from the
returned `committed_size`. This may be less than the amount of data the
client previously sent.
Calling `Write()` on a resource name that was previously written and
finalized could cause an error, depending on whether the underlying service
allows over-writing of previously written resources.
When the client closes the request channel, the service will respond with
a `WriteResponse`. The service will not view the resource as `complete`
until the client has sent a `WriteRequest` with `finish_write` set to
`true`. Sending any requests on a stream after sending a request with
`finish_write` set to `true` will cause an error. The client **should**
check the `WriteResponse` it receives to determine how much data the
service was able to commit and whether the service views the resource as
`complete` or not.

the next `Write()` call.
If the resource does not exist (i.e., the resource has been deleted, or the
first `Write()` has not yet reached the service), this method returns the
error `NOT_FOUND`.
The client **may** call `QueryWriteStatus()` at any time to determine how
much data has been processed for this resource. This is useful if the
client is buffering data and needs to know which data can be safely
evicted. For any sequence of `QueryWriteStatus()` calls for a given
resource name, the sequence of returned `committed_size` values will be
non-decreasing.
