[−][src]Struct tracing::span::Attributes
Attributes provided to a Subscriber
describing a new span when it is
created.
Implementations
impl<'a> Attributes<'a>
[src]
pub fn new(
metadata: &'static Metadata<'static>,
values: &'a ValueSet<'a>
) -> Attributes<'a>
[src]
metadata: &'static Metadata<'static>,
values: &'a ValueSet<'a>
) -> Attributes<'a>
Returns Attributes
describing a new child span of the current span,
with the provided metadata and values.
pub fn new_root(
metadata: &'static Metadata<'static>,
values: &'a ValueSet<'a>
) -> Attributes<'a>
[src]
metadata: &'static Metadata<'static>,
values: &'a ValueSet<'a>
) -> Attributes<'a>
Returns Attributes
describing a new span at the root of its own trace
tree, with the provided metadata and values.
pub fn child_of(
parent: Id,
metadata: &'static Metadata<'static>,
values: &'a ValueSet<'a>
) -> Attributes<'a>
[src]
parent: Id,
metadata: &'static Metadata<'static>,
values: &'a ValueSet<'a>
) -> Attributes<'a>
Returns Attributes
describing a new child span of the specified
parent span, with the provided metadata and values.
pub fn metadata(&self) -> &'static Metadata<'static>
[src]
Returns a reference to the new span's metadata.
pub fn values(&self) -> &ValueSet<'a>
[src]
Returns a reference to a ValueSet
containing any values the new span
was created with.
pub fn is_root(&self) -> bool
[src]
Returns true if the new span should be a root.
pub fn is_contextual(&self) -> bool
[src]
Returns true if the new span's parent should be determined based on the current context.
If this is true and the current thread is currently inside a span, then that span should be the new span's parent. Otherwise, if the current thread is not inside a span, then the new span will be the root of its own trace tree.
pub fn parent(&self) -> Option<&Id>
[src]
Returns the new span's explicitly-specified parent, if there is one.
Otherwise (if the new span is a root or is a child of the current span), returns false.
pub fn record(&self, visitor: &mut dyn Visit)
[src]
Records all the fields in this set of Attributes
with the provided
Visitor.
pub fn contains(&self, field: &Field) -> bool
[src]
Returns true
if this set of Attributes
contains a value for the
given Field
.
pub fn is_empty(&self) -> bool
[src]
Returns true if this set of Attributes
contains no values.
