Function parse_expression_range

crates/ruff_python_parser/src/lib.rs:159–169

Parses a Python expression for the given range in the source. This function allows to specify the range of the expression in the source code, other than that, it behaves exactly like [`parse_expression`]. # Example Parsing one of the numeric literal which is part of an addition expression: ``` use ruff_python_parser::parse_expression_range; # use ruff_text_size::{TextRange, TextSize}; let par

(
    source: &str,
    range: TextRange,
)

/// assert!(parsed.is_ok());
/// ```
pub fn parse_expression_range(
    source: &str,
    range: TextRange,
) -> Result<Parsed<ModExpression>, ParseError> {
    let source = &source[..range.end().to_usize()];
    Parser::new_starts_at(source, range.start(), ParseOptions::from(Mode::Expression))
        .parse()
        .try_into_expression()
        .unwrap()
        .into_result()
}

/// Parses a Python expression as if it is parenthesized.
