Struct Prefix 

pub struct Prefix { /* private fields */ }

The membership prefixes a server uses, in rank order, highest first.

Parsed from PREFIX=(ov)@+, which pairs each mode letter with the character that shows it in a NAMES reply.

Implementations

impl Prefix

pub fn parse(value: &str) -> Option<Self>

Parse a PREFIX value. A malformed value leaves the default in place, because guessing here silently corrupts every member list.

pub fn char_for_mode(&self, mode: char) -> Option<char>

The prefix character a mode letter grants, such as o giving @.

pub fn mode_for_char(&self, prefix: char) -> Option<char>

The mode letter a prefix character stands for, such as @ meaning o.

pub fn is_membership_mode(&self, mode: char) -> bool

True when this mode letter grants membership status rather than setting a channel mode.

pub fn rank(&self, prefix: char) -> Option<usize>

How highly a prefix ranks, counting from zero for the highest. Used to sort a member list.

pub fn split<'a>(&self, entry: &'a str) -> (&'a str, &'a str)

Split the leading prefixes off a NAMES entry, giving ("@+", "nick").

With multi-prefix an entry carries every prefix the member holds; without it, only the highest. Both split the same way.

Trait Implementations

impl Clone for Prefix

fn clone(&self) -> Prefix

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Prefix

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

Formats the value using the given formatter.

impl Default for Prefix

fn default() -> Self

Returns the “default value” for a type.

impl Eq for Prefix

impl PartialEq for Prefix

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