Struct tantivy::positions::PositionSerializer
source · [−]pub struct PositionSerializer<W: Write> { /* private fields */ }
Expand description
The PositionSerializer is in charge of serializing all of the positions of all of the terms of a given field.
It is valid to call write_position_delta more than once per term.
Implementations
sourceimpl<W: Write> PositionSerializer<W>
impl<W: Write> PositionSerializer<W>
sourcepub fn new(positions_wrt: W) -> PositionSerializer<W>
pub fn new(positions_wrt: W) -> PositionSerializer<W>
Creates a new PositionSerializer writing into the given positions_wrt.
sourcepub fn written_bytes(&self) -> u64
pub fn written_bytes(&self) -> u64
Returns the number of bytes written in the positions write object at this point. When called before writing the positions of a term, this value is used as start offset. When called after writing the positions of a term, this value is used as a end offset.
sourcepub fn write_positions_delta(&mut self, positions_delta: &[u32])
pub fn write_positions_delta(&mut self, positions_delta: &[u32])
Writes all of the given positions delta.
sourcepub fn close_term(&mut self) -> Result<()>
pub fn close_term(&mut self) -> Result<()>
Close the positions for the given term.
