Struct Topic 

pub struct Topic { /* private fields */ }

Implementations

impl Topic

pub fn parse(s: &str) -> Result<Self, TopicError>

Parse topic from string slice.

Errors

Returns error if string contains invalid chars or too large.

Examples found in repository

examples/parse_topic.rs (line 4)

fn main() {
    let t_sys = Topic::parse("$SYS/dev/cpu/+").unwrap();
    println!("t_sys: {:?}", t_sys);
    assert!(t_sys.is_match("$SYS/dev/cpu/01"));
}

pub fn is_match(&self, s: &str) -> bool

Returns true if this topic matches string slice.

Examples found in repository

examples/parse_topic.rs (line 6)

fn main() {
    let t_sys = Topic::parse("$SYS/dev/cpu/+").unwrap();
    println!("t_sys: {:?}", t_sys);
    assert!(t_sys.is_match("$SYS/dev/cpu/01"));
}

pub const fn topic(&self) -> &String

Used as a string slice.

pub fn len(&self) -> usize

Get topic length.

pub fn is_empty(&self) -> bool

Returns true if topic is empty.

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

Used as byte slice.

Trait Implementations

impl Clone for Topic

fn clone(&self) -> Topic

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Topic

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

Formats the value using the given formatter.

impl Default for Topic

fn default() -> Topic

Returns the “default value” for a type.

impl Hash for Topic

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Topic

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

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Topic

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

impl PartialOrd for Topic

fn partial_cmp(&self, other: &Topic) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
