Struct dash_sdk::platform::MockContextProvider

pub struct MockContextProvider { /* private fields */ }
Expand description

Mock ContextProvider that can read quorum keys from files.

Use [dash_sdk::SdkBuilder::with_dump_dir()] to generate quorum keys files.

Implementations§

§

impl MockContextProvider

pub fn new() -> MockContextProvider

Create a new instance of MockContextProvider.

This instance can be used to read quorum keys from files. You need to configure quorum keys dir using MockContextProvider::quorum_keys_dir() before using this instance.

In future, we may add more methods to this struct to allow setting expectations.

pub fn quorum_keys_dir(&mut self, quorum_keys_dir: Option<PathBuf>)

Set the directory where quorum keys are stored.

This directory should contain quorum keys files generated using [dash_sdk::SdkBuilder::with_dump_dir()].
