Trait python_ast::ast::node::Node

pub trait Node {
    // Provided methods
    fn lineno(&self) -> Option<usize> { ... }
    fn col_offset(&self) -> Option<usize> { ... }
    fn end_lineno(&self) -> Option<usize> { ... }
    fn end_col_offset(&self) -> Option<usize> { ... }
    fn error_message<S1: Into<String>, S2: Into<String>>(
        &self,
        mod_name: S1,
        message: S2
    ) -> String { ... }
}

A trait for AST elements that represent a position in a source file. Implementing this trait allows an ergonomic means of extracting line and column information from an item.

Provided Methods

fn lineno(&self) -> Option<usize>

A method for getting the starting line number of the node. This may not exist for all node types.

fn col_offset(&self) -> Option<usize>

A method for getting the starting column of the node. This may not exist for all node types.

fn end_lineno(&self) -> Option<usize>

A method for getting the ending line number of the node. This may not exist for all node types.

fn end_col_offset(&self) -> Option<usize>

A method for getting the ending column of the node. This may not exist for all node types.

fn error_message<S1: Into<String>, S2: Into<String>>( &self, mod_name: S1, message: S2 ) -> String

Generate an error message for the current code, adding line and column number.

Object Safety

This trait is not object safe.
