BoundedRange constructs a bounded range of ledgers with a fixed starting ledger and ending ledger.

CoreBuildVersion executes the "stellar-core version" command and parses its output to extract the core version The output of the "version" command is expected to be a multi-line string where the first line is the core version in format "vX.Y.Z-*".

CoreProtocolVersion retrieves the ledger protocol version from the specified stellar-core binary.

NewBufferedStorageBackend returns a new BufferedStorageBackend instance.

NewCaptive returns a new CaptiveStellarCore instance.

NewCaptiveCoreToml constructs a new CaptiveCoreToml instance based off the configuration in `params`.

NewCaptiveCoreTomlFromData constructs a new CaptiveCoreToml instance by merging configuration from the toml data and the configuration provided by `params`.
