Struct rpki_rtr::pdu::CacheReset

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

Cache reset is a response to a serial query indicating unavailability.

If a cache doesn’t have information available that reaches back to the serial number indicated in the serial query, it responds with a cache reset.

Implementations

impl CacheReset

pub const PDU: u8 = 7u8

The PDU type for a cache reset.

pub fn new(version: u8) -> Self

Creates a cache reset.

impl CacheReset

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

Writes a value to a writer.

impl CacheReset

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 CacheReset

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

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

impl AsRef<[u8]> for CacheReset

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

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

impl Default for CacheReset

fn default() -> CacheReset

Returns the “default value” for a type.
