pub enum TextTransformFn {
    None,
    Uppercase,
    Lowercase,
    Custom(Arc<dyn Fn(&Txt) -> Cow<'_, Txt> + Sync + Send>),
}

Variants

None

No transform.

Uppercase

To UPPERCASE.

Lowercase

to lowercase.

Custom(Arc<dyn Fn(&Txt) -> Cow<'_, Txt> + Sync + Send>)

Implementations

impl TextTransformFn

pub fn transform<'t>(&self, text: &'t Txt) -> Cow<'t, Txt>

Apply the text transform.

Returns Cow::Owned if the text was changed.

pub fn custom( fn_: impl Fn(&Txt) -> Cow<'_, Txt> + Send + Sync + 'static, ) -> TextTransformFn

New Custom.

Trait Implementations

impl Clone for TextTransformFn

fn clone(&self) -> TextTransformFn

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TextTransformFn

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

Formats the value using the given formatter.

impl PartialEq for TextTransformFn

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