Struct try_runtime_core::common::state::LiveState

pub struct LiveState {
    pub uri: String,
    pub at: Option<String>,
    pub pallet: Vec<String>,
    pub hashed_prefixes: Vec<String>,
    pub child_tree: bool,
}

A Live variant for State

Fields

uri: String

The url to connect to.

at: Option<String>

The block hash at which to fetch the state.

If non provided, then the latest finalized head is used.

pallet: Vec<String>

A pallet to scrape. Can be provided multiple times. If empty, entire chain state will be scraped.

This is equivalent to passing xx_hash_64(pallet) to --hashed_prefixes.

hashed_prefixes: Vec<String>

Storage entry key prefixes to scrape and inject into the test externalities. Pass as 0x prefixed hex strings. By default, all keys are scraped and included.

child_tree: bool

Fetch the child-keys as well.

Default is false, if specific --pallets are specified, true otherwise. In other words, if you scrape the whole state the child tree data is included out of the box. Otherwise, it must be enabled explicitly using this flag.

Implementations

impl LiveState

pub fn at<Block: BlockT>(&self) -> Result<Option<Block::Hash>>

where <Block::Hash as FromStr>::Err: Debug,

Return the at block hash as a Hash, if it exists.

pub async fn to_prev_block_live_state<Block: BlockT>(self) -> Result<LiveState>

where <Block::Hash as FromStr>::Err: Debug,

Converts this LiveState into a LiveState for the previous block.

Useful for opertations like when you want to execute a block, but also need the state of the block before it.

Trait Implementations

impl Args for LiveState

fn group_id() -> Option<Id>

Append to Command so it can update self.

impl Clone for LiveState

fn clone(&self) -> LiveState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LiveState

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