Struct TestChainMeta

Source 
pub struct TestChainMeta { /* private fields */ }
👎Deprecated since 8.1.0: Deprecated in favor of concordium-smart-contract-testing.
Expand description

Placeholder for the context chain meta data. All the fields are optionally set and the getting an unset field will result in test failing. For most cases it is used as part of either TestInitContext or TestReceiveContext. Use only in unit tests!

Defaults to having all of the fields unset

Implementations§

Source§

impl TestChainMeta

Source

pub fn empty() -> Self

👎Deprecated since 8.1.0: Deprecated in favor of concordium-smart-contract-testing.

Create an TestChainMeta where every field is unset, and getting any of the fields will result in fail!.

Source

pub fn set_slot_time(&mut self, value: SlotTime) -> &mut Self

👎Deprecated since 8.1.0: Deprecated in favor of concordium-smart-contract-testing.

Set the block slot time
