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>),
}

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 mut MetadataValue<Ascii>)

An ascii metadata key and value.

Binary(&'a MetadataKey<Binary>, &'a mut MetadataValue<Binary>)

A binary metadata key and value.
