Struct EnvironmentArgs 

pub struct EnvironmentArgs<C: ChainSpecParser> {
    pub datadir: DatadirArgs,
    pub config: Option<PathBuf>,
    pub chain: Arc<C::ChainSpec>,
    pub db: DatabaseArgs,
    pub static_files: StaticFilesArgs,
    pub storage: StorageArgs,
}

Struct to hold config and datadir paths

Fields

datadir: DatadirArgs

Parameters for datadir configuration

config: Option<PathBuf>

The path to the configuration file to use.

chain: Arc<C::ChainSpec>

The chain this node is running.

Possible values are either a built-in chain or the path to a chain specification file.

db: DatabaseArgs

All database related arguments

static_files: StaticFilesArgs

All static files related arguments

storage: StorageArgs

Storage mode configuration (v2 vs v1/legacy)

Implementations

impl<C: ChainSpecParser> EnvironmentArgs<C>

pub fn storage_settings(&self) -> StorageSettings

Returns the storage settings for new database initialization.

Determined by the --storage.v2 flag (defaults to true). Existing databases retain whatever settings are persisted in their metadata (checked during genesis init).

pub fn init<N: CliNodeTypes>( &self, access: AccessRights, runtime: Runtime, ) -> Result<Environment<N>>

where C: ChainSpecParser<ChainSpec = N::ChainSpec>,

Initializes environment according to AccessRights and returns an instance of Environment.

The provided runtime is used for parallel storage I/O.

Trait Implementations

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
