EndBlock

Struct EndBlock 

Source
pub struct EndBlock;
Expand description

END sentinel — marks the end of the block stream.

The END block has no fields and no body. Its presence on the wire is signaled solely by the block type byte (0xFF) in the block frame header. The bcp_wire::BlockFrame::read_from method returns None when it encounters an END block, terminating the read loop.

Unlike other block types that carry TLV-encoded fields, EndBlock is a zero-field struct. Its encode_body always returns an empty vec and its decode_body succeeds only on empty input.

Wire layout:

┌──────────────────────────────────────┐
│ block_type = 0xFF (varint, 2 bytes)  │
│ (no flags, no content_len, no body)  │
└──────────────────────────────────────┘

Implementations§

Source§

impl EndBlock

Source

pub fn encode_body(&self) -> Vec<u8>

Serialize the END block body — always empty.

Source

pub fn decode_body(_buf: &[u8]) -> Result<Self, TypeError>

Deserialize an END block from a body buffer.

Succeeds on empty input. Non-empty input is accepted but ignored, since a future spec revision could attach trailing metadata to the END sentinel.
