| 104 | Constructs a parser that uses the @ref | ||
| 105 | config parameters installed on the | ||
| 106 | provided `ctx`. | ||
| 107 | |||
| 108 | The parser will attempt to allocate | ||
| 109 | the required space on startup, with the | ||
| 110 | amount depending on the @ref config | ||
| 111 | parameters, and will not perform any | ||
| 112 | further allocations, except for Brotli | ||
| 113 | decoder instances, if enabled. | ||
| 114 | |||
| 115 | Depending on which compression algorithms | ||
| 116 | are enabled in the @ref config, the parser | ||
| 117 | will attempt to access the corresponding | ||
| 118 | decoder services on the same `ctx`. | ||
