Struct Buffer 

pub struct Buffer { /* private fields */ }

An immutable buffer which contains a valid domain.

The internal storage is a [u8; 255] array with the following layout:

• bytes 0-253: domain name content
• byte 254: length of the domain name (0-254)

This fixed-size design allows the Buffer to be used in no_std and no-alloc environments without requiring heap allocation.

Example

use hostaddr::{Domain, Buffer};

let domain: Domain<Buffer> = Domain::try_from("example.com").unwrap();
assert_eq!(domain.as_inner().as_str(), "example.com");

Implementations

impl Buffer

pub fn as_str(&self) -> &str

Returns the domain as a str.

pub const fn const_as_str(&self) -> &str

Returns the domain as a str.

Example

use hostaddr::{Buffer, Domain};

let domain: Domain<Buffer> = "example.com".parse().unwrap();
assert_eq!("example.com", domain.into_inner().const_as_str());

pub const fn as_bytes(&self) -> &[u8]

Returns the domain as a [u8]

pub const fn push(&mut self, byte: u8) -> Result<(), u8>

Push a u8 to the buffer.

let domain: Domain<Buffer> = "example.com".parse().unwrap();
let bytes: &[u8] = (&domain.into_inner()).into();

impl<'a> From<&'a Buffer> for &'a str

fn from(value: &'a Buffer) -> &'a str

use hostaddr::{Buffer, Domain};

let domain: Domain<Buffer> = "example.com".parse().unwrap();
let str: &str = (&domain.into_inner()).into();

impl From<Buffer> for Domain<Buffer>

fn from(value: Buffer) -> Domain<Buffer>

Converts to this type from the input type.

impl From<Buffer> for String

fn from(value: Buffer) -> String

Converts to this type from the input type.

impl From<Buffer> for Vec<u8>

fn from(value: Buffer) -> Vec<u8>

Converts to this type from the input type.

impl From<Domain<Buffer>> for Buffer

fn from(value: Domain<Buffer>) -> Buffer

Converts to this type from the input type.

impl Hash for Buffer

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 Buffer

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

impl PartialEq for Buffer

fn eq(&self, other: &Buffer) -> 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.

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

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

fn lt(&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.
