Trait Name 

pub trait Name: Sized + AsRef<str> {
    const KIND: &'static str;
    const MAX_LEN: usize = 64;

    // Provided methods
    fn validate_char(offset: usize, ch: char) -> Result<(), NameError> { ... }
    fn validate(s: &str) -> Result<(), NameError> { ... }
}

The validation contract shared by every name kind in the system.

Implementers pick the permitted character class and length cap by overriding Self::validate_char and Self::MAX_LEN. The default Self::validate implementation enforces the shared “non-empty, legal identifier start, every character passes validate_char” rule.

Required Associated Constants

const KIND: &'static str

Human-readable kind label, used in error messages and Debug.

Provided Associated Constants

const MAX_LEN: usize = 64

Maximum byte length (UTF-8). Default 64 — override when a larger ceiling is natural (plan names, for example).

Provided Methods

fn validate_char(offset: usize, ch: char) -> Result<(), NameError>

Called once per character to decide membership.

The default admits ASCII identifier characters plus - and ., which is a reasonable class for almost every name kind we ship.

fn validate(s: &str) -> Result<(), NameError>

Validate the given string as a name of this kind.

Called from each newtype’s constructor. Implementations that need stricter or looser rules override Self::validate_char and / or this method wholesale.

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.
