Implementations

impl FileProviderType

pub fn file_part_prefix_mut(&mut self) -> Option<&mut String>

Get a mutable reference to the file part prefix for this file provider.

File part prefixes are inserted after the partition prefix, before the file part number.

Returns

Returns None if this file provider does not support attaching file part prefixes.

pub fn get_path_or_file( &self, args: FileProviderArgs, ) -> Result<FileProviderReturn, PolarsError>

Trait Implementations

impl Clone for FileProviderType

fn clone(&self) -> FileProviderType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileProviderType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FileProviderType

fn deserialize<__D>( __deserializer: __D, ) -> Result<FileProviderType, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for FileProviderType

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FileProviderType

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

impl Serialize for FileProviderType

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
