Trait Implementations

impl From<&SstableBuilderOptions> for InMemWriter

fn from(options: &SstableBuilderOptions) -> Self

Converts to this type from the input type.

impl SstableWriter for InMemWriter

type Output = (Bytes, SstableMeta)

fn write_block<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, block: &'life1 [u8], _meta: &'life2 BlockMeta, ) -> Pin<Box<dyn Future<Output = HummockResult<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Write an SST block to the writer.

fn write_block_bytes<'life0, 'life1, 'async_trait>( &'life0 mut self, block: Bytes, _meta: &'life1 BlockMeta, ) -> Pin<Box<dyn Future<Output = HummockResult<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

fn finish<'async_trait>( self, meta: SstableMeta, ) -> Pin<Box<dyn Future<Output = HummockResult<Self::Output>> + Send + 'async_trait>>

where Self: 'async_trait,

Finish writing the SST.

fn data_len(&self) -> usize

Get the length of data that has already been written.
