Implementations

impl<'a> WriteBatch<'a>

pub fn put_bytes<C: Column + ColumnName>( &mut self, key: C::Index, bytes: &[u8] ) -> Result<()>

pub fn delete<C: Column + ColumnName>(&mut self, key: C::Index) -> Result<()>

pub fn put<C: TypedColumn + ColumnName>( &mut self, key: C::Index, value: &C::Type ) -> Result<()>

fn get_cf<C: Column + ColumnName>(&self) -> &'a ColumnFamily

fn delete_range_cf<C: Column>( &mut self, cf: &ColumnFamily, from: C::Index, to: C::Index ) -> Result<()>

Adds a [from, to) range deletion entry to the batch.

Note that the [from, to) deletion range of WriteBatch::delete_range_cf is different from [from, to] of Database::delete_range_cf as we makes the semantics of Database::delete_range_cf matches the blockstore purge logic.
