Struct HostName

pub struct HostName { /* private fields */ }

Host name, limited to 255 characters.

Commonly it is valid utf-8 string, but due to potential encoding differences, it is possible that name cannot be interpreted as utf-8 string. In this case user is encouraged to use as_bytes method and perform conversion by himself.

fmt

• Debug trait outputs byte content.

• Display trait outputs content as string, if possible, otherwise fallbacks to byte slice.

Implementations

impl HostName

pub const fn new() -> Self

Creates new empty string name

pub const fn capacity() -> usize

Returns host name size limit.

pub const fn name(name: [u8; 255]) -> Self

Initializes name from buffer.

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

Returns name as byte slice

pub fn as_str(&self) -> Result<&str, &[u8]>

Returns name as string, checking whether it is valid utf-8 before.

In case of underlying name not to be valid string, returns byte slice with content.

On windows it never fails.

impl HostName

pub fn get() -> Option<HostName>

Retrieves host’s name.

Trait Implementations

impl Borrow<[u8]> for HostName

fn borrow(&self) -> &[u8]

Immutably borrows from an owned value.

impl Clone for HostName

fn clone(&self) -> HostName

Returns a copy of the value.

impl Ord for HostName

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