Struct Topic

pub struct Topic(/* private fields */);

Tag type to route messagse to the right handler. Should be printable 0-terminated ASCII chars.

Implementations

impl Topic

pub fn new(buf: TopicInner) -> Self

Wraps a raw array topic.

pub fn from_str(s: &str) -> Self

Parses a str if valid.

Panics

If the str has a length greater than TOPIC_LEN.

pub const fn from_const_str(s: &'static str) -> Self

pub fn inner(&self) -> &TopicInner

pub fn into_inner(&self) -> TopicInner

pub fn str_len(&self) -> usize

Returns the length of the “string part”.

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

Returns a slice of the string bytes of the topic.

pub fn is_standard(&self) -> bool

Returns if it’s a standard topic ID.

pub fn as_str(&self) -> Option<&str>

If the topic is a standard topic, returns it as a str.

Trait Implementations

impl BorshDeserialize for Topic

fn deserialize_reader<__R: Read>(reader: &mut __R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for Topic

fn serialize<__W: Write>(&self, writer: &mut __W) -> Result<(), Error>

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 Display for Topic

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

Formats the value using the given formatter.

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: &Topic) -> 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.
