Trait with casing extensions.

Required Associated Types

type Character: Copy + Eq

Required Methods

fn upper(&self, _: Locale) -> Cow<'_, Self>

Turns Self to upper case avoiding allocations if nothing would change.

fn lower(&self, _: Locale) -> Cow<'_, Self>

Turns Self to lower case avoiding allocations if nothing would change.

fn capitalized(&self, _: Locale) -> Cow<'_, Self>

Turns Self to its capitalized version, turning the first character to upper case and the rest to lower case.

fn camel( &self, separators: Separator<&[Self::Character]>, mode: Camel, _: Locale, ) -> Cow<'_, Self>

Turns Self to camel case using the passed Separator to know which symbols should mark a new word.

fn separated( &self, separator: Separator<Self::Character>, _: Locale, ) -> Cow<'_, Self>

Turns Self to a case separated by the given separator, using Separator('_') would turn to snake case, using Separator('-') would turn to dashed case.

fn header(&self, _: Locale) -> Cow<'_, Self>

Turns Self to header case, where each word is separated by '-' and starts with an upper case character. Upper case characters after the first are not lower cased.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
