Enum nix_compat::wire::bytes::writer::BytesPacketPosition

enum BytesPacketPosition {
    Size(usize),
    Payload(u64),
    Padding(usize),
}

Models the position inside a “bytes wire packet” that the writer is in. It can be in three different stages, inside size, payload or padding fields. The number tracks the number of bytes written inside the specific field. There shall be no ambiguous states, at the end of a stage we immediately move to the beginning of the next one:

• Size(LEN_SIZE) must be expressed as Payload(0)
• Payload(self.payload_len) must be expressed as Padding(0)

Padding(padding_len) means we’re at the end of the bytes wire packet.

Variants

Size(usize)

Payload(u64)

Padding(usize)

Trait Implementations

impl Clone for BytesPacketPosition

fn clone(&self) -> BytesPacketPosition

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BytesPacketPosition

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for BytesPacketPosition

fn eq(&self, other: &BytesPacketPosition) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
