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