Struct soroban_env_host::storage::Footprint

source ·

pub struct Footprint(pub FootprintMap);

Expand description

Describes the total set of LedgerKeys that a given transaction will access, as well as the AccessType governing each key.

A Footprint must be provided in order to run a transaction that accesses any LedgerKeys in FootprintMode::Enforcing. If a transaction has an unknown Footprint it can be calculated by running a “preflight” execution in FootprintMode::Recording, against a suitably fresh SnapshotSource.
