Trait PrimaryId 

pub trait PrimaryId: Copy + Debug {
    // Required method
    fn as_str(&self) -> &'static str;
}

Trait for primary category identifiers

This is the minimal trait needed for error codes. Just implement .as_str().

Examples

use waddling_errors::PrimaryId;

#[derive(Debug, Clone, Copy)]
enum Primary {
    Syntax,
    Type,
}

impl PrimaryId for Primary {
    fn as_str(&self) -> &'static str {
        match self {
            Primary::Syntax => "SYNTAX",
            Primary::Type => "TYPE",
        }
    }
}

Required Methods

fn as_str(&self) -> &'static str

Get the primary category name (e.g., “SYNTAX”, “TYPE”)

Must be uppercase, 2-12 characters.

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.
