Enum hinku::ParseError

pub enum ParseError<E> {
    EndOfStream,
    UnexpectedToken {
        span: Span,
    },
    Custom {
        span: Span,
        error: Vec<E>,
    },
}

Represents a parsing error.

Variants

EndOfStream

The end of the stream was reached unexpectedly.

UnexpectedToken

An unexpected token was encountered.

Fields of UnexpectedToken

span: Span

Span of the unexpected token.

Custom

An user-defined error occurred.

Fields of Custom

span: Span

Part of the input that caused the error.

error: Vec<E>

List of error context. The first element is "deeper" into the parser and the last more "general."
