Struct WriterBuilder 

pub struct WriterBuilder {
    schema: Schema,
    codec: Option<CompressionCodec>,
    capacity: usize,
    fingerprint_strategy: Option<FingerprintStrategy>,
}

Builder to configure and create a Writer.

Fields

schema: Schema

codec: Option<CompressionCodec>

capacity: usize

fingerprint_strategy: Option<FingerprintStrategy>

Implementations

impl WriterBuilder

pub fn new(schema: Schema) -> Self

Create a new builder with default settings.

The Avro schema used for writing is determined as follows:

1. If the Arrow schema metadata contains avro::schema (see SCHEMA_METADATA_KEY), that JSON is used verbatim.
2. Otherwise, the Arrow schema is converted to an Avro record schema.

pub fn with_fingerprint_strategy(self, strategy: FingerprintStrategy) -> Self

Set the fingerprinting strategy for the stream writer. This determines the per-record prefix format.

pub fn with_compression(self, codec: Option<CompressionCodec>) -> Self

Change the compression codec.

pub fn with_capacity(self, capacity: usize) -> Self

Sets the capacity for the given object and returns the modified instance.

pub fn build<W, F>(self, writer: W) -> Result<Writer<W, F>, ArrowError>

where W: Write, F: AvroFormat,

Create a new Writer with specified AvroFormat and builder options. Performs one‑time startup (header/stream init, encoder plan).
