Struct DummyCardanoDbBuilder 

pub struct DummyCardanoDbBuilder { /* private fields */ }

A DummyCardanoDbBuilder builder.

Implementations

impl DummyCardanoDbBuilder

pub fn new(dir_name: &str) -> Self

DummyCardanoDbBuilder factory, will create a folder with the given dirname in the system temp directory, if it exists already it will be cleaned.

pub fn with_immutables( &mut self, immutables: &[ImmutableFileNumber], ) -> &mut Self

Set the immutables file number that will be used to generate the immutable files, for each number three files will be generated (a ‘chunk’, a ‘primary’ and a ‘secondary’ file).

pub fn with_non_immutables(&mut self, non_immutables: &[&str]) -> &mut Self

Set filenames to write to the db that doesn’t follow the immutable file name scheme.

pub fn with_legacy_ledger_snapshots( &mut self, snapshot_slot_numbers: &[u64], ) -> &mut Self

Set legacy ledger state snapshot slot numbers to write to the db in the ‘ledger’ subdirectory.

pub fn with_in_memory_ledger_snapshots( &mut self, snapshot_slot_numbers: &[u64], ) -> &mut Self

Set the slot numbers of utxo-hd in-memory snapshot folders to write to the db in the ‘ledger’ subdirectory.

pub fn with_non_ledger_files(&mut self, files: &[&str]) -> &mut Self

Set filenames to write to the ‘ledger’ subdirectory that are not ledger snapshots.

pub fn set_ledger_file_size(&mut self, file_size: u64) -> &mut Self

Set the size of all ledger files written by build to the given file_size in bytes.

Note: for types of ledger state snapshots that have more than one file, the size is evenly split across all files:

• Legacy snapshots: not divided as it’s a single file
• In-memory snapshots: divided by three

pub fn with_volatile_files(&mut self, files: &[&str]) -> &mut Self

Set volatile files to write to the db in the ‘volatile’ subdirectory.

pub fn set_volatile_file_size(&mut self, file_size: u64) -> &mut Self

Set the size of all volatile files written by build to the given file_size in bytes.

pub fn append_immutable_trio(&mut self) -> &mut Self

Makes build add another trio of immutables file, that won’t be included in its returned vec, to simulate the last 3 ‘uncompleted / wip’ files that can be found in a cardano immutable db.

pub fn set_immutable_trio_file_size(&mut self, trio_file_size: u64) -> &mut Self

Set the size of all immutable files written by build to the given file_size in bytes.

Note: by default, the size of the produced files is less than 1 kb.

pub fn build(&self) -> DummyCardanoDb

Build a DummyCardanoDb.
