pub fn options(self, options: WriterOptions) -> Self

Overrides writer options wholesale.

pub fn codec_parallelism(self, parallelism: CodecParallelism) -> Self

Selects the runtime policy for independent chain compression jobs.

pub fn chain_compression(self, compression: ChainCompression) -> Self

Selects the per-chain compression.

pub fn time_compression(self, compression: TimeCompression) -> Self

Selects the time-table compression.

pub fn hierarchy_compression(self, compression: HierarchyCompression) -> Self

Selects compression for the hierarchy declaration block.

pub fn dynamic_alias_encoding(self, encoding: DynamicAliasEncoding) -> Self

Chooses the legacy or current dynamic-alias index representation.

pub fn wrap_with_zlib(self, wrap: bool) -> Self

Toggles the outer gzip wrapper.

pub fn timescale_exponent(self, exponent: i8) -> Self
