Struct rpki_rtr::pdu::CacheResponse

#[repr(packed)]
pub struct CacheResponse { /* private fields */ }

The cache response starts a sequence of payload PDUs with data.

Implementations

impl CacheResponse

pub const PDU: u8 = 3u8

The payload type of a cache response.

pub fn new(version: u8, state: State) -> Self

Creates a new cache response for the given state.

impl CacheResponse

pub async fn write<A: AsyncWrite + Unpin>(&self, a: &mut A) -> Result<(), Error>

Writes a value to a writer.

impl CacheResponse

pub fn version(&self) -> u8

Returns the value of the version field of the header.

pub fn session(&self) -> u16

Returns the value of the session field of the header.

Note that this field is used for other purposes in some PDU types.

pub fn size() -> u32

Returns the PDU size.

The size is returned as a u32 since that type is used in the header.

pub async fn read<Sock: AsyncRead + Unpin>(
    sock: &mut Sock
) -> Result<Self, Error>

Reads a value from a reader.

If a value with a different PDU type is received, returns an error.

pub async fn try_read<Sock: AsyncRead + Unpin>(
    sock: &mut Sock
) -> Result<Result<Self, Header>, Error>

Tries to read a value from a reader.

If a different PDU type is received, returns the header as the error case of the ok case.

pub async fn read_payload<Sock: AsyncRead + Unpin>(
    header: Header,
    sock: &mut Sock
) -> Result<Self, Error>

Reads only the payload part of a value from a reader.

Assuming that the header was already read and is passed via header, the function reads the rest of the PUD from the reader and returns the complete value.

Trait Implementations

impl AsMut<[u8]> for CacheResponse

fn as_mut(&mut self) -> &mut [u8]

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<[u8]> for CacheResponse

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Default for CacheResponse

fn default() -> CacheResponse

Returns the “default value” for a type.
