Struct ParseError 

pub struct ParseError {
    pub message: String,
    pub range: Range,
    pub expected: Vec<String>,
    pub found: String,
    pub recovery_hint: Option<String>,
}

Error information with recovery context for comprehensive Perl parsing error handling.

This structure encapsulates all information needed for intelligent error recovery in the Perl parser, enabling continued parsing after syntax errors and providing detailed diagnostic information for IDE integration.

Fields

message: String

range: Range

expected: Vec<String>

List of token types that were expected at this position

found: String

The token that was actually found instead of expected

recovery_hint: Option<String>

Optional hint for error recovery or fixing the issue
