Struct CsvSource

pub struct CsvSource { /* private fields */ }

Expand description

CSV Data source. Contains location of data file, and computes CSV metadata. Can be turned into CsvReader object.

Implementations§

Source §

impl CsvSource

Source

pub fn new<L: Into<FileLocator>>(loc: L) -> Result<CsvSource>

Create a new CsvSource object with provided file location. This constructor will analyze (sniff) the file to detect its metadata (delimiter, quote character, preamble, etc.)

§Error

Fails if unable to open the file at the provided location, or if CSV analysis fails.

Source

pub fn metadata(&self) -> &Metadata

Return the compute Metadata for this CSV source.
