Expand description

A set of fields recorded by a span.

Implementations

source

impl<'a> Record<'a>

source

pub fn new(values: &'a ValueSet<'a>) -> Self

Constructs a new Record from a ValueSet.

source

pub fn record(&self, visitor: &mut dyn Visit)

Records all the fields in this Record with the provided Visitor.

source

pub fn contains(&self, field: &Field) -> bool

Returns true if this Record contains a value for the given Field.

source

pub fn is_empty(&self) -> bool

Returns true if this Record contains no values.
