Implementations

impl Pos

pub fn new(line: u32, character: u32) -> Self

新しい位置を生成して返す

pub fn next_char(&mut self)

次の文字位置に移動する (改行ではない文字が続くことを想定している)

use mylang_token::pos;

let mut pos = pos!(3;7);
pos.next_char();

let expected = pos!(3;8);
assert_eq!(pos, expected);

pub fn next_line(&mut self)

次の行の先頭に移動する

use mylang_token::pos;

let mut pos = pos!(1;8);
pos.next_line();

let expected = pos!(2;0);
assert_eq!(pos, expected);

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<'de> Deserialize<'de> for Pos

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Pos

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

Formats the value using the given formatter.

impl From<Pos> for Range

fn from(pos: Pos) -> Self

始端と終端が同じ位置の範囲に変換する

impl PartialEq for Pos

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

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Pos

impl StructuralPartialEq for Pos
