Struct Overlay 

Source 
pub struct Overlay { /* private fields */ }
Expand description

An in-memory overlay of merkle tree and b-tree changes.

Implementations§

Source§

impl Overlay

Source

pub fn root(&self) -> Root

Get the merkle root at this overlay.

Source§

impl Overlay

Source

pub fn commit<T: HashAlgorithm>(self, nomt: &Nomt<T>) -> Result<()>

Commit the changes from this overlay to the underlying database.

This function will block until all ongoing sessions and commits have finished.

This will return an error if I/O fails or if the changeset is no longer valid, or if the overlay has an uncommitted parent. An overlay may be invalidated by a competing commit or rollback.

Source

pub fn try_commit_nonblocking<T: HashAlgorithm>( self, nomt: &Nomt<T>, ) -> Result<Option<Self>>

Commit the changes from this overlay to the underlying database without blocking.

This function will return Ok(Some(Self)) if there are ongoing sessions and commits.

This will return an error if I/O fails or if the changeset is no longer valid, or if the overlay has an uncommitted parent. An overlay may be invalidated by a competing commit or rollback.
