Struct cannyls::lump::LumpId

pub struct LumpId(_);

Lumpの識別子(128bit幅).

Methods

impl LumpId

pub const SIZE: usize

識別子のバイト幅.

pub fn new(id: u128) -> Self

新しいLumpIdインスタンスを生成する.

Examples

use cannyls::lump::LumpId;

assert_eq!(LumpId::new(0x12_3456).to_string(), "00000000000000000000000000123456");

// 16進数文字列からも生成可能
assert_eq!("123456".parse::<LumpId>().unwrap(), LumpId::new(0x12_3456));

pub fn as_u128(&self) -> u128

識別子の値(128bit整数)を返す.

Trait Implementations

impl Clone for LumpId

fn clone(&self) -> LumpId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Ord for LumpId

fn cmp(&self, other: &LumpId) -> 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.

impl Eq for LumpId

impl Copy for LumpId

impl PartialOrd<LumpId> for LumpId

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl PartialEq<LumpId> for LumpId

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

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

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

This method tests for !=.

impl Display for LumpId

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

Formats the value using the given formatter.

impl Debug for LumpId

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

Formats the value using the given formatter.

impl Hash for LumpId

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 FromStr for LumpId

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self>

16進数表記の数値からLumpIdを生成する.

数値の"128bit整数"として扱われ、先頭のゼロは省略可能（"ab12"と"00ab12"は等価）.

Errors

以下のいずれかの場合には、種類がErrorKind::InvalidInputのエラーが返される:

• 文字列が16進数表記の整数値を表していない
• 文字列の長さが32文字を超えている

Examples

use std::str::{self, FromStr};
use cannyls::ErrorKind;
use cannyls::lump::LumpId;

assert_eq!(LumpId::from_str("00ab12").ok(),
           Some(LumpId::new(0xab12)));

assert_eq!(LumpId::from_str("foo_bar").err().map(|e| *e.kind()),
           Some(ErrorKind::InvalidInput));

let large_input = str::from_utf8(&[b'a', 33][..]).unwrap();
assert_eq!(LumpId::from_str(large_input).err().map(|e| *e.kind()),
           Some(ErrorKind::InvalidInput));
