Struct Options

pub struct Options {
    pub src_database_url: String,
    pub dst_database_url: String,
    pub chain_id: Option<String>,
    pub poll_ms: Duration,
    pub genesis_json: PathBuf,
    pub exit_on_catchup: bool,
}

This struct represents the command-line options

Fields

src_database_url: String

PostgreSQL database connection string for the source database with raw events

dst_database_url: String

PostgreSQL database connection string for the destination database with compiled data

chain_id: Option<String>

Filter for only events with this chain ID.

poll_ms: Duration

The rate at which to poll for changes, in milliseconds.

genesis_json: PathBuf

A file path for the genesis file to use when initializing the indexer.

exit_on_catchup: bool

By default, the program will run as a daemon, continuously polling the src database for new events. If –exit-on-catchup is set, the program will instead exit after it has indexed all events in the src database. Useful for batch jobs.

Trait Implementations

impl Args for Options

fn augment_args<'b>(__clap_app: Command<'b>) -> Command<'b>

Append to [Command] so it can instantiate Self.

fn augment_args_for_update<'b>(__clap_app: Command<'b>) -> Command<'b>

Append to [Command] so it can update self.

impl Clone for Options

fn clone(&self) -> Options

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl CommandFactory for Options

fn into_app<'b>() -> Command<'b>

Deprecated, replaced with CommandFactory::command

fn into_app_for_update<'b>() -> Command<'b>

Deprecated, replaced with CommandFactory::command_for_update

fn command<'help>() -> App<'help>

Build a [Command] that can instantiate Self.

fn command_for_update<'help>() -> App<'help>

Build a [Command] that can update self.

impl Debug for Options

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

Formats the value using the given formatter.

impl FromArgMatches for Options

fn from_arg_matches(__clap_arg_matches: &ArgMatches) -> Result<Self, Error>

Instantiate Self from [ArgMatches], parsing the arguments as needed.

fn from_arg_matches_mut( __clap_arg_matches: &mut ArgMatches, ) -> Result<Self, Error>

Instantiate Self from [ArgMatches], parsing the arguments as needed.

fn update_from_arg_matches( &mut self, __clap_arg_matches: &ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.

fn update_from_arg_matches_mut( &mut self, __clap_arg_matches: &mut ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.

impl Parser for Options

fn parse() -> Self

Parse from std::env::args_os(), exit on error

fn try_parse() -> Result<Self, Error>

Parse from std::env::args_os(), return Err on error.
