Enum DataFormat 

#[non_exhaustive]
pub enum DataFormat {
    Csv,
    JsonLines,
    Unsupported(String),
}

The format of a stream of data.

TODO: We might add a StreamFormat that handles “wrapper” formats like gzip or bzip2.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Csv

Comma-separated values.

JsonLines

One JSON value per line. See JSON Lines.

Unsupported(String)

Another data format that we don’t support. This will be the file extension, minus any leading “.” character.

Trait Implementations

impl Clone for DataFormat

fn clone(&self) -> DataFormat

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DataFormat

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DataFormat

fn default() -> DataFormat

Returns the “default value” for a type.

impl Display for DataFormat

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Format data formats as their file extensions, without the leading “.”.

impl FromStr for DataFormat

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self>

Parses a string s to return a value of this type.

impl PartialEq for DataFormat

fn eq(&self, other: &DataFormat) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
