Struct sc_cli::PruningParams

pub struct PruningParams {
    pub state_pruning: DatabasePruningMode,
    pub blocks_pruning: DatabasePruningMode,
}

Parameters to define the pruning mode

Fields

state_pruning: DatabasePruningMode

Specify the state pruning mode.

This mode specifies when the block’s state (ie, storage) should be pruned (ie, removed) from the database.

Possible values: ‘archive’ Keep the state of all blocks. ‘archive-canonical’ Keep only the state of finalized blocks. number Keep the state of the last number of finalized blocks.

blocks_pruning: DatabasePruningMode

Specify the blocks pruning mode.

This mode specifies when the block’s body (including justifications) should be pruned (ie, removed) from the database.

Possible values: ‘archive’ Keep all blocks. ‘archive-canonical’ Keep only finalized blocks. number Keep the last number of finalized blocks.

Implementations

impl PruningParams

pub fn state_pruning(&self) -> Result<Option<PruningMode>>

Get the pruning value from the parameters

Examples found in repository

src/config.rs (line 247)

	fn state_pruning(&self) -> Result<Option<PruningMode>> {
		self.pruning_params()
			.map(|x| x.state_pruning())
			.unwrap_or_else(|| Ok(Default::default()))
	}

pub fn blocks_pruning(&self) -> Result<BlocksPruning>

Get the block pruning value from the parameters

Examples found in repository

src/config.rs (line 257)

	fn blocks_pruning(&self) -> Result<BlocksPruning> {
		self.pruning_params()
			.map(|x| x.blocks_pruning())
			.unwrap_or_else(|| Ok(BlocksPruning::KeepFinalized))
	}

Trait Implementations

impl Args for PruningParams

fn group_id() -> Option<Id>

Report the ArgGroup::id for this set of arguments

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

Append to Command so it can instantiate Self.

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

Append to Command so it can update self.

impl Clone for PruningParams

fn clone(&self) -> PruningParams

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PruningParams

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

Formats the value using the given formatter.

impl FromArgMatches for PruningParams

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 PartialEq<PruningParams> for PruningParams

fn eq(&self, other: &PruningParams) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
