Struct node_testing::bench::BenchDb

pub struct BenchDb { /* fields omitted */ }

Pre-initialized benchmarking database.

This is prepared database with genesis and keyring that can be cloned and then used for any benchmarking.

Implementations

impl BenchDb

pub fn with_key_types(
    database_type: DatabaseType,
    keyring_length: usize,
    key_types: KeyTypes
) -> Self

New immutable benchmarking database.

See BenchDb::new method documentation for more information about the purpose of this structure.

pub fn new(database_type: DatabaseType, keyring_length: usize) -> Self

New immutable benchmarking database.

This will generate database files in random temporary directory and keep it there until struct is dropped.

You can clone this database or you can create_context from it (which also does clone) to run actual operation against new database which will be identical to the original.

pub fn generate_inherents(&mut self, client: &Client) -> Vec<OpaqueExtrinsic>

Generate list of required inherents.

Uses already instantiated Client.

pub fn block_content(
    &self,
    content: BlockContent,
    client: &Client
) -> BlockContentIterator<'_>

Iterate over some block content with transaction signed using this database keyring.

pub fn client(&mut self) -> Client

Get cliet for this database operations.

pub fn generate_block(&mut self, content: BlockContent) -> Block

Generate new block using this database.

pub fn path(&self) -> &Path

Database path.

pub fn create_context(&self, profile: Profile) -> BenchContext

Clone this database and create context for testing/benchmarking.

Trait Implementations

impl Clone for BenchDb

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
