Struct tezos_smart_rollup::testing::prelude::MockHost

pub struct MockHost { /* private fields */ }

The runtime host when not running in wasm.

Implementations

impl MockHost

pub fn with_address(address: &SmartRollupAddress) -> MockHost

Create a new instance of the MockHost, specifying the rollup address.

pub fn add_transfer( &mut self, payload: impl Michelson, metadata: &TransferMetadata )

Append an internal message to the current inbox.

pub fn add_external(&mut self, message: impl BinWriter)

Append an external message to the current inbox.

pub fn set_preimage(&mut self, preimage: Vec<u8>) -> [u8; 33]

Make a preimage available to the reveal_data channel.

pub fn run_level(&mut self, kernel_run: fn(_: &mut MockHost)) -> u32

Runs kernel_run against the current level’s inbox.

• Includes the StartOfLevel, InfoPerLevel & EndOfLevel messages.
• Returns the level the kernel was run at.

pub fn level(&self) -> u32

Returns the level of the next kernel_run.

pub fn info_per_level(&self) -> &InfoPerLevel

Returns the InfoPerLevel of the next kernel_run.

pub fn outbox_at(&self, level: u32) -> Vec<Vec<u8>>

Show the outbox at the given level

Trait Implementations

impl AsMut<HostState> for MockHost

fn as_mut(&mut self) -> &mut HostState

Converts this type into a mutable reference of the (usually inferred) input type.

impl Debug for MockHost

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for MockHost

fn default() -> MockHost

Returns the “default value” for a type.

impl From<HostState> for MockHost

fn from(state: HostState) -> MockHost

Converts to this type from the input type.
