Struct HttpResponse 

pub struct HttpResponse {
    pub status_code: u32,
    pub status_text: CompactString,
    pub headers: SmallVec<[(CompactString, CompactString); 8]>,
    pub body: Bytes,
}

Simplified HTTP response type extracted from picohttp::Response. Owns all data (no borrowed lifetime) so it can be stored and used freely.

Zero-copy / zero-alloc optimizations:

• status_text: CompactString inlines short strings like “OK” (no heap alloc)
• headers: SmallVec stacks ≤8 header pairs (typical case), spills to heap only for many headers
• body: Bytes enables zero-copy slicing and avoids clone() on large responses

Fields

status_code: u32

HTTP status code (e.g. 200, 404, 500).

status_text: CompactString

Status text (e.g. “OK”, “Not Found”). CompactString: inline for ≤24 bytes.

headers: SmallVec<[(CompactString, CompactString); 8]>

Response headers as (name, value) pairs. SmallVec: stack for ≤8 pairs.

body: Bytes

Response body. Bytes: zero-copy slicing, cheap clone (Arc ref count).
