Enum FileFormat

pub enum FileFormat {
    Csv {
        with_header: bool,
    },
    Json,
    Control,
    Custom {
        extension: String,
    },
}

Used internally by algorithms to determine whether they can support writing a checkpoint file of the designated type.

When checkpoints are specified by Driver::checkpoint, the file format is determined from the file extension of the supplied path.

Implementations

impl FileFormat

pub fn from_path(path: &Path) -> Self

pub fn from_os_str(file_extension: &OsStr) -> Self

pub fn to_extension(&self) -> String

pub fn unsupported_error(&self) -> Error

Will generate an io::Error indicating that the file format is unsupported

Trait Implementations

impl Clone for FileFormat

fn clone(&self) -> FileFormat

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FileFormat

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

Formats the value using the given formatter.

impl PartialEq for FileFormat

fn eq(&self, other: &FileFormat) -> 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.
