Struct ErrorCode 

pub struct ErrorCode(pub u16);

A unique error code for each error type.

Error codes are formatted as E followed by a 4-digit zero-padded number (e.g., E0001, E0042). They are assigned by category:

• E0001-E0099: Lexer errors (tokenization)
• E0100-E0199: Parser errors (syntax)
• E0200-E0399: Semantic errors (types, names, scopes)
• E0400-E0499: Struct/enum errors
• E0500-E0599: Control flow errors
• E0600-E0699: Match errors
• E0700-E0799: Intrinsic errors
• E0800-E0899: Literal/operator errors
• E0900-E0999: Array errors
• E1000-E1099: Linker/target errors
• E1100-E1199: Preview feature errors
• E9000-E9999: Internal compiler errors

Once assigned, error codes must never change to maintain stability for documentation, search engines, and user bookmarks.

Trait Implementations

impl Clone for ErrorCode

fn clone(&self) -> ErrorCode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ErrorCode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ErrorCode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for ErrorCode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ErrorCode

fn eq(&self, other: &ErrorCode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
