Trait SmallChar 

pub trait SmallChar:
    Copy
    + Default
    + Ord
    + Eq
    + Hash
    + Debug {
    const ZERO: Self;

    // Required methods
    fn from_char(c: char) -> Option<Self>;
    fn to_char(self) -> char;
}

Trait for character types that can be stored in SmallString.

This trait abstracts over different character representations:

• u16: UTF-16 code unit (2 bytes), compatible with ITensors.jl’s SmallString
• char: Full Unicode code point (4 bytes), supports all Unicode characters

Default is u16 for memory efficiency and ITensors.jl compatibility.

Required Associated Constants

const ZERO: Self

The null/zero value for this character type.

Required Methods

fn from_char(c: char) -> Option<Self>

Convert from a Rust char. Returns None if the character cannot be represented in this type.

fn to_char(self) -> char

Convert to a Rust char.

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.
