Struct lang_util::position::LexerPosition

pub struct LexerPosition {
    pub source_id: FileId,
    pub offset: TextSize,
}

A position in the lexer’s input

Fields

source_id: FileId

Source id

offset: TextSize

Raw byte offset

Implementations

impl LexerPosition

pub fn new(source_id: FileId, offset: TextSize) -> Self

Create a new LexerPosition

Parameters

• source_id: source id
• offset: byte offset in the input

pub fn new_raw<E: Debug>(
    source_id: FileId,
    offset: impl TryInto<u32, Error = E>
) -> Self

Create a new LexerPosition

Parameters

• source_id: source id
• offset: raw byte offset in the input

Panics

Panics if the offset can’t be converted to a u32.

Trait Implementations

impl Clone for LexerPosition

fn clone(&self) -> LexerPosition

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LexerPosition

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

Formats the value using the given formatter.

impl Default for LexerPosition

fn default() -> LexerPosition

Returns the “default value” for a type.

impl Display for LexerPosition

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

Formats the value using the given formatter.

impl From<LexerPosition> for FileId

fn from(value: LexerPosition) -> Self

Converts to this type from the input type.

impl From<LexerPosition> for TextSize

fn from(value: LexerPosition) -> Self

Converts to this type from the input type.

impl Hash for LexerPosition

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 LexerPosition

fn cmp(&self, other: &LexerPosition) -> 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) -> Selfwhere
    Self: PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<LexerPosition> for LexerPosition

fn eq(&self, other: &LexerPosition) -> 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<LexerPosition> for LexerPosition

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