Struct MockWriter 

pub struct MockWriter {
    hasher: RwLock<Hasher>,
    expected_digest: B3Digest,
    closed: bool,
}

Available on crate feature mocks only.

Implements super::Writer and panics if the expected data wasn’t written on close.

Fields

hasher: RwLock<Hasher>

expected_digest: B3Digest

closed: bool

Implementations

impl MockWriter

pub fn new(expected_digest: B3Digest) -> Self

Constructs a new MockWriter expecting the passed digest.

Trait Implementations

impl AsyncWrite for MockWriter

fn poll_write( self: Pin<&mut Self>, _cx: &mut Context<'_>, buf: &[u8], ) -> Poll<Result<usize>>

Attempt to write bytes from buf into the object.

fn poll_flush(self: Pin<&mut Self>, _cx: &mut Context<'_>) -> Poll<Result<()>>

Attempts to flush the object, ensuring that any buffered data reach their destination.

fn poll_shutdown( self: Pin<&mut Self>, _cx: &mut Context<'_>, ) -> Poll<Result<()>>

Initiates or attempts to shut down this writer, returning success when the I/O connection has completely shut down.

fn poll_write_vectored( self: Pin<&mut Self>, cx: &mut Context<'_>, bufs: &[IoSlice<'_>], ) -> Poll<Result<usize, Error>>

Like poll_write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

Determines if this writer has an efficient poll_write_vectored implementation.

impl Drop for MockWriter

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Writer for MockWriter

fn close<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<B3Digest>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Signal there’s no more data to be written, and return the digest of the contents written.
