[−][src]Struct rdkafka::message::BorrowedHeaders
Borrowed message headers
The BorrowedHeaders struct provides a read-only access to headers owned by OwnedMessage
struct or by a OwnedHeaders struct.
Trait Implementations
impl Headers for BorrowedHeaders[src]
fn count(&self) -> usize[src]
fn get(&self, idx: usize) -> Option<(&str, &[u8])>[src]
fn get_as<V: FromBytes + ?Sized>(
&self,
idx: usize
) -> Option<(&str, Result<&V, V::Error>)>[src]
&self,
idx: usize
) -> Option<(&str, Result<&V, V::Error>)>
Same as Headers::get, but the value of the header will be converted to the specified type. If the conversion fails, an error will be returned instead. Read more
