Struct tantivy::fastfield::FastFieldSerializer

pub struct FastFieldSerializer { /* fields omitted */ }

FastFieldSerializer is in charge of serializing fastfields on disk.

Fast fields are encoded using bit-packing.

FastFieldWriters are in charge of pushing the data to the serializer. The serializer expects to receive the following calls.

• new_u64_fast_field(...)
• add_val(...)
• add_val(...)
• add_val(...)
• ...
• close_field()
• new_u64_fast_field(...)
• add_val(...)
• ...
• close_field()
• close()

Methods

impl FastFieldSerializer

pub fn from_write(write: WritePtr) -> Result<FastFieldSerializer>

Constructor

pub fn new_u64_fast_field(
    &mut self,
    field: Field,
    min_value: u64,
    max_value: u64
) -> Result<FastSingleFieldSerializer<CountingWriter<WritePtr>>>

Start serializing a new u64 fast field

pub fn new_u64_fast_field_with_idx(
    &mut self,
    field: Field,
    min_value: u64,
    max_value: u64,
    idx: usize
) -> Result<FastSingleFieldSerializer<CountingWriter<WritePtr>>>

Start serializing a new u64 fast field

pub fn close(self) -> Result<()>

Closes the serializer

After this call the data must be persistently save on disk.
