Trait UtfExt 

pub trait UtfExt: UtfExtSealed {
    type UtfSlice: ?Sized;

    // Required method
    fn try_encode_utf8(self, bs: &mut [u8]) -> Option<&mut Self::UtfSlice>;
}

Required Associated Types

type UtfSlice: ?Sized

Required Methods

fn try_encode_utf8(self, bs: &mut [u8]) -> Option<&mut Self::UtfSlice>

Encode the character into the given buffer; return None if the buffer is too short.

Dyn Compatibility

This trait is dyn compatible.

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