Struct scylla::serialize::writers::CellValueBuilder

pub struct CellValueBuilder<'buf> { /* private fields */ }

Allows appending bytes to a non-null, non-unset cell.

This object needs to be dropped in order for the value to be correctly serialized. Failing to drop this value will result in a payload that will not be parsed by the database correctly, but otherwise should not cause data to be misinterpreted.

Implementations

impl<'buf> CellValueBuilder<'buf>

pub fn append_bytes(&mut self, bytes: &[u8])

Appends raw bytes to this cell.

pub fn make_sub_writer(&mut self) -> CellWriter<'_>

Appends a sub-value to the end of the current contents of the cell and returns an object that allows to fill it in.

pub fn finish(self) -> Result<WrittenCellProof<'buf>, CellOverflowError>

Finishes serializing the value.

Fails if the constructed cell size overflows the maximum allowed CQL cell size (which is i32::MAX).
