Struct AnnotationColumn 

pub(crate) struct AnnotationColumn {
    pub display: usize,
    pub file: usize,
}

Fields

display: usize

the (0-indexed) column for display purposes, counted in characters, not utf-8 bytes

file: usize

the (0-indexed) column in the file, counted in characters, not utf-8 bytes.

this may be different from self.display, e.g. if the file contains hard tabs, because we convert tabs to spaces for error messages.

for example:

(hard tab)hello
          ^ this is display column 4, but file column 1

we want to keep around the correct file offset so that column numbers in error messages are correct. (motivated by https://github.com/rust-lang/rust/issues/109537)

Implementations

impl AnnotationColumn

pub(crate) fn from_loc(loc: &Loc) -> AnnotationColumn

Trait Implementations

impl Clone for AnnotationColumn

fn clone(&self) -> AnnotationColumn

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AnnotationColumn

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

Formats the value using the given formatter.

impl Default for AnnotationColumn

fn default() -> AnnotationColumn

Returns the “default value” for a type.

impl Ord for AnnotationColumn

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

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

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for AnnotationColumn

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for AnnotationColumn

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Copy for AnnotationColumn

impl Eq for AnnotationColumn

impl StructuralPartialEq for AnnotationColumn

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
