Implementations

impl NameGenerator

pub fn from_func( func: impl Fn(usize) -> Result<PlSmallStr, PolarsError> + Send + Sync + 'static, ) -> NameGenerator

Trait Implementations

impl Clone for NameGenerator

fn clone(&self) -> NameGenerator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NameGenerator

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

Formats the value using the given formatter.

impl Eq for NameGenerator

impl Hash for NameGenerator

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 NameGenerator

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