Struct Query 

pub struct Query {
    pub user: Option<String>,
    pub hosts: Vec<String>,
    pub long: bool,
    pub port: u16,
}

A parsed finger query.

Represents the structured result of parsing a finger query string like "user@host", "@host", or "user@host1@host2".

Fields

user: Option<String>

The user to query. None means list all users.

hosts: Vec<String>

The host(s) to query. The last host is the connection target. Multiple hosts indicate a forwarding chain (RFC 1288).

long: bool

Whether to request verbose output (sends /W prefix).

port: u16

TCP port to connect on. Default is 79.

Implementations

impl Query

pub fn parse(input: Option<&str>, long: bool, port: u16) -> Query

Parse a query string into a Query.

Examples

• "user@host" -> user=Some(“user”), hosts=[“host”]
• "@host" -> user=None, hosts=[“host”]
• "user@host1@host2" -> user=Some(“user”), hosts=[“host1”, “host2”]
• "user" -> user=Some(“user”), hosts=[“localhost”]
• "" or None -> user=None, hosts=[“localhost”]

pub fn target_host(&self) -> &str

Returns the host to connect to (the last host in the chain).

Trait Implementations

impl Clone for Query

fn clone(&self) -> Query

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Query

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

Formats the value using the given formatter.

impl PartialEq for Query

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