Struct grin_chain::store::Batch

pub struct Batch<'a> { /* fields omitted */ }

An atomic batch in which all changes can be committed all at once or discarded on error.

Methods

impl<'a> Batch<'a>

pub fn head(&self) -> Result<Tip, Error>

pub fn tail(&self) -> Result<Tip, Error>

pub fn head_header(&self) -> Result<BlockHeader, Error>

Header of the block at the head of the block chain (not the same thing as header_head).

pub fn header_head(&self) -> Result<Tip, Error>

Head of the header chain (not the same thing as head_header).

pub fn get_sync_head(&self) -> Result<Tip, Error>

pub fn save_head(&self, t: &Tip) -> Result<(), Error>

pub fn save_body_head(&self, t: &Tip) -> Result<(), Error>

pub fn save_body_tail(&self, t: &Tip) -> Result<(), Error>

pub fn save_header_head(&self, t: &Tip) -> Result<(), Error>

pub fn save_sync_head(&self, t: &Tip) -> Result<(), Error>

pub fn reset_sync_head(&self) -> Result<(), Error>

Reset sync_head to the current head of the header chain.

pub fn reset_header_head(&self) -> Result<(), Error>

Reset header_head to the current head of the body chain.

pub fn get_block(&self, h: &Hash) -> Result<Block, Error>

get block

pub fn block_exists(&self, h: &Hash) -> Result<bool, Error>

pub fn save_block(&self, b: &Block) -> Result<(), Error>

Save the block and the associated input bitmap. Note: the block header is not saved to the db here, assumes this has already been done.

pub fn delete_block(&self, bh: &Hash) -> Result<(), Error>

Delete a full block. Does not delete any record associated with a block header.

pub fn save_block_header(&self, header: &BlockHeader) -> Result<(), Error>

pub fn save_output_pos(     &self,     commit: &Commitment,     pos: u64 ) -> Result<(), Error>

pub fn get_output_pos(&self, commit: &Commitment) -> Result<u64, Error>

pub fn delete_output_pos(&self, commit: &[u8]) -> Result<(), Error>

pub fn get_previous_header(     &self,     header: &BlockHeader ) -> Result<BlockHeader, Error>

pub fn get_block_header(&self, h: &Hash) -> Result<BlockHeader, Error>

pub fn save_block_sums(&self, h: &Hash, sums: &BlockSums) -> Result<(), Error>

pub fn get_block_sums(&self, h: &Hash) -> Result<BlockSums, Error>

pub fn get_block_input_bitmap(&self, bh: &Hash) -> Result<Bitmap, Error>

pub fn commit(self) -> Result<(), Error>

Commits this batch. If it's a child batch, it will be merged with the parent, otherwise the batch is written to db.

pub fn child(&mut self) -> Result<Batch, Error>

Creates a child of this batch. It will be merged with its parent on commit, abandoned otherwise.
