sourcepub fn to_vec(&self) -> Result<Vec<u8>, Error>
pub fn to_vec(&self) -> Result<Vec<u8>, Error>
Returns the remaining contents as a Vec<u8>
. If no bytes have been
read, this returns the entire contents.
sourcepub fn to_string(&self) -> Result<String, Error>
pub fn to_string(&self) -> Result<String, Error>
Returns the remaining contents as a string. If no bytes have been read, this returns the entire contents.
sourcepub fn into_vec(self) -> Result<Vec<u8>, Error>
pub fn into_vec(self) -> Result<Vec<u8>, Error>
Returns the remaining contents as a Vec<u8>
. If no bytes have been
read, this returns the entire contents.
sourcepub fn into_string(self) -> Result<String, Error>
pub fn into_string(self) -> Result<String, Error>
Returns the remaining contents as a string. If no bytes have been read, this returns the entire contents.

sourcepub fn with_buffer_size(
self,
size_in_bytes: usize
) -> Contents<Database, Config>
pub fn with_buffer_size( self, size_in_bytes: usize ) -> Contents<Database, Config>
Sets the maximum buffer size in bytes and returns self
. When buffering
reads from the database, requests will be made to fill at-most
size_in_bytes
of memory.
sourcepub fn last_appended_at(
&self
) -> Option<LimitedResolutionTimestamp<Nanoseconds, BonsaiEpoch>>
pub fn last_appended_at( &self ) -> Option<LimitedResolutionTimestamp<Nanoseconds, BonsaiEpoch>>
Returns the timestamp that the last data was written to the file. Returns None if the file is empty.
