Struct FilePosition

pub struct FilePosition(/* private fields */);

A 32-bit numerical value, starting from zero, that indicates the location of a byte in a file.

FilePosition is primarily used by the lexer to record the source location in the preprocessed translation unit of every token. This information is later used when emitting diagnostics to include the relevant source code.

A 4 GB C source file should be enough for anybody, right?

Trait Implementations

Performs the += operation.

impl Clone for FilePosition

fn clone(&self) -> FilePosition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FilePosition

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

Formats the value using the given formatter.

impl Default for FilePosition

fn default() -> FilePosition

Returns the “default value” for a type.

impl Display for FilePosition

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

Formats the value using the given formatter.

impl From<FilePosition> for u32

fn from(val: FilePosition) -> Self

Converts to this type from the input type.

impl From<i32> for FilePosition

fn from(value: i32) -> Self

Converts to this type from the input type.

impl From<u32> for FilePosition

fn from(value: u32) -> Self

Converts to this type from the input type.

impl From<usize> for FilePosition

fn from(value: usize) -> Self

Converts to this type from the input type.

impl Ord for FilePosition

fn cmp(&self, other: &FilePosition) -> 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 FilePosition

fn eq(&self, other: &FilePosition) -> 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 FilePosition

fn partial_cmp(&self, other: &FilePosition) -> 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.

Performs the - operation.

impl Sub for FilePosition

type Output = FilePosition

The resulting type after applying the - operator.

fn sub(self, rhs: FilePosition) -> Self::Output
