Implementations

impl<'a> TopicFilter

pub fn levels(&'a self) -> TopicLevels<'a>

Trait Implementations

impl Clone for TopicFilter

fn clone(&self) -> TopicFilter

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TopicFilter

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

Formats the value using the given formatter.

impl Display for TopicFilter

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

Formats the value using the given formatter.

impl FromStr for TopicFilter

type Err = TopicParseError

The associated error which can be returned from parsing.

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

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

impl PartialEq for TopicFilter

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