Enum CompositeKind 

pub enum CompositeKind {
    Option,
    Result,
    Tuple,
    Struct(Cow<'static, str>),
}

A description of the kind of a composite key.

Variants

Option

An Option, which always contains a single field.

Result

An Result, which reports two fields – the first for the Ok type, and the second for the Err type.

Tuple

A sequence of fields.

Struct(Cow<'static, str>)

A sequence of fields, identified by the fully qualified name. E.g., "std::time::SystemTime" is the value that the SystemTime’s KeyEncoding implementation reports.

Trait Implementations

impl Clone for CompositeKind

fn clone(&self) -> CompositeKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompositeKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CompositeKind

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CompositeKind

fn eq(&self, other: &CompositeKind) -> 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 CompositeKind

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for CompositeKind
