Struct LexError 

pub struct LexError {
    pub code: u16,
    pub message: String,
    pub range: TextRange,
}

A lexer-level diagnostic: a code (matching DiagCode discriminants in cyrs-diag) plus a message and byte range. Emitted by validate_tokens for errors that can only be detected after the DFA run — unterminated literals, invalid escape sequences, etc.

cyrs-syntax does not depend on cyrs-diag (spec §3.1), so the code is carried as a plain u16.

Fields

code: u16

Numeric discriminant of the corresponding DiagCode in cyrs-diag (e.g. 4 for E0004).

message: String

Human-readable message (rustc-style lower-case initial, no trailing period).

range: TextRange

Byte range of the offending lexeme.
