Implementations

impl TransformFn

pub fn apply(&self, value: &str) -> String

Apply this transformation to value and return the result.

Trait Implementations

impl Clone for TransformFn

fn clone(&self) -> TransformFn

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransformFn

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

Formats the value using the given formatter.

impl PartialEq for TransformFn

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