Trait StrTools 

pub trait StrTools: Sealed {
    // Required methods
    fn sub_nearest(&self, range: impl Range) -> &str;
    fn capitalise(&self) -> Cow<'_, str>;
    fn decapitalise(&self) -> Cow<'_, str>;
}

Available on crate feature string only.

The main StrTools extension trait.

Required Methods

fn sub_nearest(&self, range: impl Range) -> &str

A substring method which truncates strings at the nearest UTF-8 code rather than panicking.

Panics

This function still panics if the given range is out of bounds. It however does not panic if the passed range falls withing a UTF-8 code.

fn capitalise(&self) -> Cow<'_, str>

A string capitalize function which operates on UTF-8 strings.

fn decapitalise(&self) -> Cow<'_, str>

A string decapitalize function which operates on UTF-8 strings. This essentially does the inverse of the capitalise function.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
