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