Struct CommitBuilder 

pub struct CommitBuilder<'r, S: AsyncBlockStoreWrite> { /* private fields */ }

A Commit builder.

Implementations

impl<'r, S: AsyncBlockStoreWrite> CommitBuilder<'r, S>

pub fn prev(&mut self, prev: Cid) -> &mut Self

Set the prev commit field, which contains a link to the previous commit

pub fn rev(&mut self, time: Tid) -> &mut Self

Set the rev commit field, which is a monotonically-increasing number that can be used to signify the order in which commits are made.

pub fn bytes(&self) -> Vec<u8>

Serialize the commit as bytes for signing.

pub async fn finalize(self, sig: Vec<u8>) -> Result<Cid, Error>

Cryptographically sign the commit, ensuring it can never be mutated again.

We assume that the provided cryptographic hash is valid. If the signature is invalid, the commit will be rejected when published to the network!
