Trait sc_light::blockchain::ProvideChtRoots[−][src]

pub trait ProvideChtRoots<Block> where
    Block: Block, {
    pub fn header_cht_root(
        &self, 
        cht_size: <<Block as Block>::Header as Header>::Number, 
        block: <<Block as Block>::Header as Header>::Number
    ) -> Result<Option<<Block as Block>::Hash>, Error>;

    pub fn changes_trie_cht_root(
        &self, 
        cht_size: <<Block as Block>::Header as Header>::Number, 
        block: <<Block as Block>::Header as Header>::Number
    ) -> Result<Option<<Block as Block>::Hash>, Error>;
}

Provide CHT roots. These are stored on a light client and generated dynamically on a full client.

Required methods

pub fn header_cht_root(
    &self,
    cht_size: <<Block as Block>::Header as Header>::Number,
    block: <<Block as Block>::Header as Header>::Number
) -> Result<Option<<Block as Block>::Hash>, Error>[src]

Get headers CHT root for given block. Returns None if the block is not a part of any CHT.

pub fn changes_trie_cht_root(
    &self,
    cht_size: <<Block as Block>::Header as Header>::Number,
    block: <<Block as Block>::Header as Header>::Number
) -> Result<Option<<Block as Block>::Hash>, Error>[src]

Get changes trie CHT root for given block. Returns None if the block is not a part of any CHT.
