Struct WriteConfig 

pub struct WriteConfig {
    pub out_path: Option<PathBuf>,
    pub format: OutFormat,
    pub overwrite: bool,
    pub compression: Option<ParquetCompression>,
    pub compression_level: Option<u32>,
}

Output configuration for writing Arrow data.

Captures the output file path, format, compression settings, and overwrite behavior. Created separately from ReadStatPath, which handles only input path validation.

Fields

out_path: Option<PathBuf>

Optional output file path.

format: OutFormat

Output format (defaults to CSV).

overwrite: bool

Whether to overwrite an existing output file.

compression: Option<ParquetCompression>

Optional Parquet compression algorithm.

compression_level: Option<u32>

Optional Parquet compression level.

Implementations

impl WriteConfig

pub fn new( out_path: Option<PathBuf>, format: Option<OutFormat>, overwrite: bool, compression: Option<ParquetCompression>, compression_level: Option<u32>, ) -> Result<Self, ReadStatError>

Creates a new WriteConfig after validating the output path, format, and compression settings.

Errors

Returns ReadStatError if the output path, format, or compression settings are invalid.

fn validate_format(format: Option<OutFormat>) -> OutFormat

fn validate_out_extension( path: &Path, format: OutFormat, ) -> Result<Option<PathBuf>, ReadStatError>

Validates the output file extension matches the format.

fn validate_out_path( path: Option<PathBuf>, overwrite: bool, ) -> Result<Option<PathBuf>, ReadStatError>

Validates the output path exists and handles overwrite logic.

fn validate_compression_level( compression: ParquetCompression, compression_level: Option<u32>, ) -> Result<Option<u32>, ReadStatError>

Validates compression level is valid for the given compression algorithm.
