Struct AnalysisContext 

pub struct AnalysisContext<'a> {
    pub file_path: &'a Path,
    pub source: &'a str,
    pub ast: &'a File,
    pub config: &'a Config,
    /* private fields */
}

Context passed to rules during analysis.

Contains all information needed to analyze a single file.

Fields

file_path: &'a Path

source: &'a str

ast: &'a File

config: &'a Config

Implementations

impl<'a> AnalysisContext<'a>

pub fn new( file_path: &'a Path, source: &'a str, ast: &'a File, config: &'a Config, ) -> Self

Create a new analysis context.

pub fn line_col(&self, offset: usize) -> (usize, usize)

Get line and column from a byte offset (1-indexed).

This is O(log n) where n is the number of lines.

pub fn get_line(&self, line_num: usize) -> Option<&str>

Get the source line at the given line number (1-indexed).

pub fn line_index(&self) -> &LineIndex

Get a reference to the line index for advanced lookups.

pub fn span_to_byte_range(&self, span: Span) -> Option<(usize, usize)>

Convert a proc_macro2 span to byte range (start, end).

Returns None if the span positions are invalid.
