Enum SpanRole 

#[non_exhaustive]
pub enum SpanRole<'a> {
    Primary {
        label: Cow<'a, str>,
    },
    Supplementary {
        label: Cow<'a, str>,
    },
}

Type and label annotating a Span

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.

Primary

Primary span, usually indicating the main cause of a problem

Fields

label: Cow<'a, str>

Supplementary

Secondary span, usually indicating related information

Fields

label: Cow<'a, str>

Trait Implementations

impl<'a> Clone for SpanRole<'a>

fn clone(&self) -> SpanRole<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for SpanRole<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for SpanRole<'a>

fn eq(&self, other: &SpanRole<'a>) -> 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.
