Struct tvix_castore::blobservice::GRPCBlobService

source ·
pub struct GRPCBlobService<T> {
    instance_name: String,
    grpc_client: BlobServiceClient<T>,
}
Expand description

Connects to a (remote) tvix-store BlobService over gRPC.

Fields§

§instance_name: String§grpc_client: BlobServiceClient<T>

The internal reference to a gRPC client. Cloning it is cheap, and it internally handles concurrent requests.

Trait Implementations§

source§

impl<T> BlobService for GRPCBlobService<T>
where T: GrpcService<BoxBody> + Send + Sync + Clone + 'static, T::ResponseBody: Body<Data = Bytes> + Send + 'static, <T::ResponseBody as Body>::Error: Into<StdError> + Send, T::Future: Send,

source§

fn open_write<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Box<dyn BlobWriter>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Returns a BlobWriter, that’ll internally wrap each write in a proto::BlobChunk, which is send to the gRPC server.

source§

fn has<'life0, 'life1, 'async_trait>( &'life0 self, digest: &'life1 B3Digest, ) -> Pin<Box<dyn Future<Output = Result<bool>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Check if the service has the blob, by its content hash. On implementations returning chunks, this must also work for chunks.
source§

fn open_read<'life0, 'life1, 'async_trait>( &'life0 self, digest: &'life1 B3Digest, ) -> Pin<Box<dyn Future<Output = Result<Option<Box<dyn BlobReader>>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Request a blob from the store, by its content hash. On implementations returning chunks, this must also work for chunks.
source§

fn chunks<'life0, 'life1, 'async_trait>( &'life0 self, digest: &'life1 B3Digest, ) -> Pin<Box<dyn Future<Output = Result<Option<Vec<ChunkMeta>>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Return a list of chunks for a given blob. There’s a distinction between returning Ok(None) and Ok(Some(vec![])). The former return value is sent in case the blob is not present at all, while the second one is sent in case there’s no more granular chunks (or the backend does not support chunking). A default implementation checking for existence and then returning it does not have more granular chunks available is provided.
