Struct TokenSourceError 

#[non_exhaustive]
pub struct TokenSourceError {
    pub line: usize,
    pub column: usize,
    pub span: Option<Range<usize>>,
    pub message: String,
}

A diagnostic buffered by a token source while it was producing tokens.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

line: usize

One-based input line where the diagnostic starts.

column: usize

Zero-based column within line where the diagnostic starts.

span: Option<Range<usize>>

Half-open UTF-8 byte span of the offending input, when available.

message: String

ANTLR-compatible diagnostic message without the leading line/column.

Implementations

impl TokenSourceError

pub fn new(line: usize, column: usize, message: impl Into<String>) -> Self

Creates a token-source diagnostic at the given input position.

pub const fn with_span(self, span: Range<usize>) -> Self

Attaches the resolved half-open UTF-8 byte span.
