Struct mdsn::Address

pub struct Address {
    pub host: Option<String>,
    pub port: Option<u16>,
    pub path: Option<String>,
}

A simple struct to represent a server address, with host:port or socket path.

Fields

host: Option<String>

Host or ip address of the server.

port: Option<u16>

Port to connect to the server.

path: Option<String>

Use unix socket path to connect.

Implementations

impl Address

pub fn new(host: impl Into<String>, port: u16) -> Self

Construct server address with host and port.

Trait Implementations

impl Clone for Address

fn clone(&self) -> Address

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Address

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

Formats the value using the given formatter.

impl Default for Address

fn default() -> Address

Returns the “default value” for a type.

impl Display for Address

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

Formats the value using the given formatter.

impl FromStr for Address

type Err = DsnError

The associated error which can be returned from parsing.

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

Parses a string s to return a value of this type.

impl PartialEq for Address

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
