[−][src]Enum verify::serde::NewSpan

pub enum NewSpan<S: Span> {
    Add(Option<S>),
    Reset(Option<S>),
    NoChange,
}
This is supported on feature="serde" only.

Type returned by Spans, it dictates how the newly returned spans should be used.

It is required because Spans support hierarchy and simply a None span will reset the existing hierarchy. Without this type resetting the hierarchy and providing a new span would not be possible.

Variants

Add(Option<S>)
This is supported on feature="serde" only.

Add the Span to the existing hierarchy. If it is None, the entire hierarchy is cleared.

Reset(Option<S>)
This is supported on feature="serde" only.

Reset the existing hierarchy then applies the new span.

NoChange
This is supported on feature="serde" only.

Do nothing, and use the existing hierarchy and span if there is any.
