Struct Blob

Source 
pub struct Blob { /* private fields */ }
Expand description

A testing server implementation of an open /blob/ file.

Blob does not send the OnOpen event or handle requests until instructed to do so.

Implementations§

Source§

impl Blob

Source

pub fn fail_open_with_already_exists(self)

Fail the open request with an error indicating the blob already exists.

§Panics

Panics on error

Source

pub fn fail_open_with_not_found(self)

Fail the open request with an error indicating the blob does not exist.

§Panics

Panics on error

Source

pub fn fail_open_with_io_error(self)

Fail the open request with a generic IO error.

§Panics

Panics on error

Source

pub async fn fail_open_with_not_readable(self)

Succeeds the open request, but indicate the blob is not yet readable by not asserting the USER_0 signal on the file event handle, then asserts that the connection to the blob is closed.

§Panics

Panics on error

Source

pub async fn succeed_open_with_blob_readable(self)

Succeeds the open request, indicating that the blob is readable, then asserts that the connection to the blob is closed.

§Panics

Panics on error

Source

pub async fn expect_close(self)

Succeeds the open request, then verifies the blob is immediately closed (possibly after handling a single Close request).

§Panics

Panics on error

Source

pub async fn expect_done(self)

Asserts that the request stream closes without any further requests.

§Panics

Panics on error

Source

pub async fn expect_read(self, blob: &[u8])

Succeeds the open request, then handle read request with the given blob data.

§Panics

Panics on error

Source

pub async fn serve_contents(self, data: &[u8])

Succeeds the open request. Then handles get_attr, read, read_at, and possibly a final close requests with the given blob data.

§Panics

Panics on error

Source

pub async fn fail_write_with_corrupt(self)

Succeeds the open request, consumes the truncate request, the initial write calls, then fails the final write indicating the written data was corrupt.

§Panics

Panics on error

Source

pub fn expect_payload(self, expected: &[u8]) -> impl Future<Output = ()> + '_

Succeeds the open request, then returns a future that, when awaited, verifies the blob is truncated, written, and closed with the given expected payload.

§Panics

Panics on error
