Struct Utf8String

pub struct Utf8String(/* private fields */);

null 終端の UTF-8 文字列

Implementations

impl Utf8String

pub const EMPTY: Self

空文字列

pub fn new(s: &str) -> Option<Self>

終端の null を含まない文字列を受け取って Utf8String インスタンスを作成する

引数の文字列内の null 文字が含まれている場合には None が返される

pub fn get(&self) -> &str

このインスタンスが保持する、null 終端部分を含まない文字列を返す

pub fn into_null_terminated_bytes(self) -> Vec<u8>

このインスタンスを、null 終端部分を含むバイト列へと変換する

Trait Implementations

impl Clone for Utf8String

fn clone(&self) -> Utf8String

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Utf8String

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

Formats the value using the given formatter.

impl Decode for Utf8String

fn decode<R: Read>(reader: R) -> Result<Self>

reader から読み込んだバイト列から Self を構築する

impl Encode for Utf8String

fn encode<W: Write>(&self, writer: W) -> Result<()>

self をバイト列に変換して writer に書き込む

impl Hash for Utf8String

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 Utf8String

fn cmp(&self, other: &Utf8String) -> 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 Utf8String

fn eq(&self, other: &Utf8String) -> 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 Utf8String

fn partial_cmp(&self, other: &Utf8String) -> 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.
