Enum tonic::metadata::KeyAndValueRef [−][src]
pub enum KeyAndValueRef<'a> { Ascii(&'a MetadataKey<Ascii>, &'a MetadataValue<Ascii>), Binary(&'a MetadataKey<Binary>, &'a MetadataValue<Binary>), }
Reference to a key and an associated value in a MetadataMap
. It can point
to either an ascii or a binary (“*-bin”) key.
Variants
Ascii(&'a MetadataKey<Ascii>, &'a MetadataValue<Ascii>)
An ascii metadata key and value.
Binary(&'a MetadataKey<Binary>, &'a MetadataValue<Binary>)
A binary metadata key and value.
