Enum TraceEntry 

#[non_exhaustive]
pub enum TraceEntry {
    Step(Cow<'static, str>),
    Kv {
        key: Cow<'static, str>,
        value: String,
    },
}

One breadcrumb recorded on a Trace.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Step(Cow<'static, str>)

A narrative step, recorded by Trace::step.

Kv

A key/value pair, recorded by Trace::kv.

Fields

key: Cow<'static, str>

The key.

value: String

The value, rendered to text when the breadcrumb was recorded.

Trait Implementations

impl Clone for TraceEntry

fn clone(&self) -> TraceEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TraceEntry

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TraceEntry

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TraceEntry

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

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 TraceEntry

impl StructuralPartialEq for TraceEntry
