Implementations

impl FileId

pub fn new(raw: u32) -> Self

Create a new file identifier

Panics

panics if raw is greater than 0x7FFFFFFF

pub fn builtin(raw: u32) -> Self

Create a new file identifier for a built-in string

Panics

panics if raw is greater than 0x7FFFFFFE

pub fn number(&self) -> u32

Get the number behind this id, regardless of its type

Trait Implementations

impl Clone for FileId

fn clone(&self) -> FileId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FileId

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

Formats the value using the given formatter.

impl Default for FileId

fn default() -> Self

Returns the “default value” for a type.

impl Display for FileId

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

Formats the value using the given formatter.

impl From<FileId> for u32

fn from(value: FileId) -> Self

Converts to this type from the input type.

impl From<LexerPosition> for FileId

fn from(value: LexerPosition) -> Self

Converts to this type from the input type.

impl From<NodeSpan> for FileId

fn from(value: NodeSpan) -> Self

Converts to this type from the input type.

impl From<u32> for FileId

fn from(value: u32) -> Self

Converts to this type from the input type.

impl Hash for FileId

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for FileId

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<FileId> for FileId

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

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

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

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

impl PartialOrd<FileId> for FileId

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