Struct sc_cli::OffchainWorkerParams

pub struct OffchainWorkerParams {
    pub enabled: OffchainWorkerEnabled,
    pub indexing_enabled: bool,
}

Offchain worker related parameters.

Fields

enabled: OffchainWorkerEnabled

Should execute offchain workers on every block.

By default it’s only enabled for nodes that are authoring new blocks.

indexing_enabled: bool

Enable Offchain Indexing API, which allows block import to write to Offchain DB.

Enables a runtime to write directly to a offchain workers DB during block import.

Implementations

impl OffchainWorkerParams

pub fn offchain_worker(&self, role: &Role) -> Result<OffchainWorkerConfig>

Load spec to Configuration from OffchainWorkerParams and spec factory.

Trait Implementations

impl Debug for OffchainWorkerParams

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

Formats the value using the given formatter.

impl StructOpt for OffchainWorkerParams

fn clap<'a, 'b>() -> App<'a, 'b>

Returns clap::App corresponding to the struct.

fn from_clap(matches: &ArgMatches<'_>) -> Self

Builds the struct from clap::ArgMatches. It’s guaranteed to succeed if matches originates from an App generated by StructOpt::clap called on the same type, otherwise it must panic.

fn from_args() -> Self

Builds the struct from the command line arguments (std::env::args_os). Calls clap::Error::exit on failure, printing the error message and aborting the program.

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

Builds the struct from the command line arguments (std::env::args_os). Unlike StructOpt::from_args, returns clap::Error on failure instead of aborting the program, so calling .exit is up to you.

fn from_iter<I>(iter: I) -> Self where
    I: IntoIterator,
    <I as IntoIterator>::Item: Into<OsString>,
    <I as IntoIterator>::Item: Clone, 

Gets the struct from any iterator such as a Vec of your making. Print the error message and quit the program in case of failure.

fn from_iter_safe<I>(iter: I) -> Result<Self, Error> where
    I: IntoIterator,
    <I as IntoIterator>::Item: Into<OsString>,
    <I as IntoIterator>::Item: Clone, 

Gets the struct from any iterator such as a Vec of your making.
