Struct cranelift_isle::lexer::Pos

pub struct Pos {
    pub file: usize,
    pub offset: usize,
    pub line: usize,
    pub col: usize,
}

A source position.

Fields

file: usize

This source position’s file.

Indexes into Lexer::filenames early in the compiler pipeline, and later into TypeEnv::filenames once we get into semantic analysis.

offset: usize

This source position’s byte offset in the file.

line: usize

This source position’s line number in the file.

col: usize

This source position’s column number in the file.

Implementations

impl Pos

pub fn pretty_print(&self, filenames: &[Arc<str>]) -> String

Print this source position as file.isle:12:34.

pub fn pretty_print_line(&self, filenames: &[Arc<str>]) -> String

Print this source position as file.isle line 12.

pub fn pretty_print_with_filename(&self, filename: &str) -> String

As above for pretty_print, but with the specific filename already provided.

Trait Implementations

impl Clone for Pos

fn clone(&self) -> Pos

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Pos

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

Formats the value using the given formatter.

impl Default for Pos

fn default() -> Pos

Returns the “default value” for a type.

impl Hash for Pos

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl Ord for Pos

fn cmp(&self, other: &Pos) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<Pos> for Pos

fn eq(&self, other: &Pos) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Pos) -> bool

This method tests for !=.

impl PartialOrd<Pos> for Pos

fn partial_cmp(&self, other: &Pos) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
