Struct debris_common::input_file::InputFiles

pub struct InputFiles {
    input_files: Vec<InputFile>,
}

Keeps track of all input files and allows to make cheap copy-able spans

Fields

input_files: Vec<InputFile>

All input files which are used in this compiler

This vector is append-only and the offset of the input files is guaranteed to be increasing.

Implementations

impl InputFiles

pub fn new() -> Self

pub fn add_input(&mut self, code: Code) -> CodeId

Adds a code unit and returns its ID

pub fn get_code_ref(&self, code_id: CodeId) -> CodeRef<'_>

pub fn find_by_filename(&self, filename: &str) -> Option<CodeId>

Searches the registered InputFiles and returns the first with a matching filename

pub fn get_input(&self, code_id: CodeId) -> &Code

Gets the input file with this id

pub fn get_input_offset(&self, code_id: CodeId) -> usize

Gets the offset of the file with this id

pub fn get_total_offset(&self) -> usize

Calculates the total byte offset

fn get_span_file(&self, span: Span) -> (usize, &InputFile)

Searches for the input file that contains the given span

Returns a (index, &input_file) tuple. Since the input files are stored sorted, the search can be completed with O(log n) time complexity

pub fn get_span_code(&self, span: Span) -> CodeRef<'_>

pub fn get_span_str(&self, span: Span) -> &str

Returns the str that corresponds to a span

Panics

panics if the span is out of bounds

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

Returns the line in a file at which this span begins and the column This function starts counting at zero, so that the first character in a file is (0, 0)

Trait Implementations

impl Debug for InputFiles

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for InputFiles

fn default() -> InputFiles

Returns the “default value” for a type.
