Struct concordium_std::test_infrastructure::TestChainMeta

source · 
pub struct TestChainMeta { /* private fields */ }
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§

pub fn empty() -> Self
