Struct MockProvider 

pub struct MockProvider { /* private fields */ }

In-memory ChainProvider for unit tests.

Stores a fixed mapping of storage slot → value. Calls always return empty bytes.

Implementations

impl MockProvider

pub fn new(slots: HashMap<[u8; 32], [u8; 32]>) -> Self

Create a provider pre-loaded with slots.

Trait Implementations

impl ChainProvider for MockProvider

fn read_storage<'life0, 'async_trait>( &'life0 self, _address: [u8; 20], slot: [u8; 32], ) -> Pin<Box<dyn Future<Output = Result<[u8; 32]>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Read a 32-byte storage slot from address on this chain.

fn call<'life0, 'async_trait>( &'life0 self, _address: [u8; 20], _calldata: Bytes, ) -> Pin<Box<dyn Future<Output = Result<Bytes>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Execute a read-only call to address with the given ABI-encoded calldata.
