# Struct ethcore_rpc::v1::tests::helpers::TestSnapshotService [−] [src]

    pub struct TestSnapshotService { /* fields omitted */ }

Mocked snapshot service (used for sync info extensions).

## Methods

### `impl TestSnapshotService`
[src]

#### `fn new() -> Self`

Create a test snapshot service. Only the `status` function matters -- it'll return `Inactive` by default.

#### `fn set_status(&self, status: RestorationStatus)`

Set the restoration status.

## Trait Implementations

### `impl SnapshotService for TestSnapshotService`
[src]

#### `fn manifest(&self) -> Option<ManifestData>`

Query the most recent manifest data.

#### `fn chunk(&self, _hash: H256) -> Option<Bytes>`

Get raw chunk for a given hash.

#### `fn status(&self) -> RestorationStatus`

Ask the snapshot service for the restoration status.

#### `fn begin_restore(&self, _manifest: ManifestData)`

Begin snapshot restoration. If restoration in-progress, this will reset it. From this point on, any previous snapshot may become unavailable. Read more

#### `fn abort_restore(&self)`

Abort an in-progress restoration if there is one.

#### `fn restore_state_chunk(&self, _hash: H256, _chunk: Bytes)`

Feed a raw state chunk to the service to be processed asynchronously. no-op if not currently restoring. Read more

#### `fn restore_block_chunk(&self, _hash: H256, _chunk: Bytes)`

Feed a raw block chunk to the service to be processed asynchronously. no-op if currently restoring. Read more

#### `fn provide_canon_hashes(&self, _hashes: &[(u64, H256)])`

Give the restoration in-progress some canonical block hashes for extra verification (performed at the end) Read more

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
