Struct HandlerInfo 

pub struct HandlerInfo {
    pub typename: Cow<'static, str>,
    pub arm: Option<Cow<'static, str>>,
}

Information about a message handler being processed.

Uses Cow<'static, str> to avoid string copies on the hot path. The typename and arm are typically static strings from TypeInfo.

Fields

typename: Cow<'static, str>

The type name of the message being handled.

arm: Option<Cow<'static, str>>

The enum arm being handled, if the message is an enum.

Implementations

impl HandlerInfo

pub fn from_static(typename: &'static str, arm: Option<&'static str>) -> Self

Create a new HandlerInfo from static strings (zero-copy).

pub fn from_owned(typename: String, arm: Option<String>) -> Self

Create a new HandlerInfo from owned strings.

Trait Implementations

impl Clone for HandlerInfo

fn clone(&self) -> HandlerInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HandlerInfo

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for HandlerInfo

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for HandlerInfo

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

Formats the value using the given formatter.

impl PartialEq for HandlerInfo

fn eq(&self, other: &HandlerInfo) -> 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 Serialize for HandlerInfo

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
