`flare.qpack.static_table`

QPACK static table (RFC 9204 Appendix A).

The table holds 99 entries (indices 0..98) covering the most common HTTP/3 header field shapes (:authority, :method, :path, :scheme, :status plus a curated set of request/response headers with their canonical values). The table is read-only at compile time; the encoder picks the lowest-index match, and the decoder maps a static index back to the (name, value) pair via static_table_lookup.

Sans-I/O: pure data + pure functions.

Functions

`static_name`

def static_name(index: Int) -> StaticString

Name at index; the caller has range-checked it. A comptime switch over the table, so no table is built per call.

`static_value`

def static_value(index: Int) -> StaticString

Value at index; the caller has range-checked it.

`static_table_lookup`

def static_table_lookup(index: Int) -> HpackHeader

Return the (name, value) pair at index in the RFC 9204 Appendix A static table.

Raises Error on out-of-range indices; the QPACK decoder surfaces this as a malformed-field-line failure.

`static_table_find`

def static_table_find(name: String, value: String) -> Int

Return the lowest static-table index for the (name, value) pair, or -1 if none matches.

Unrolled at compile time against the literal table. Lookup is case-sensitive on both fields -- callers normalise header names to lowercase before consulting the table (HTTP/3 mandates lowercase field names on the wire, RFC 9114 §4.2).

`static_table_find_name`

def static_table_find_name(name: String) -> Int

Return the lowest static-table index whose name is name, independent of value. Used by the encoder when no full (name, value) match exists but the name itself is present in the static table (literal-with-name-reference path).

Aliases

comptime QPACK_STATIC_TABLE_SIZE = Int(99)

Number of entries in the RFC 9204 Appendix A static table.

Lookups are comptime-unrolled over the literal table, so neither side builds the table at run time.
