ResponseParser

Struct ResponseParser 

Source
pub struct ResponseParser { /* private fields */ }
Expand description

有状态增量响应解析器

解决 parse_response 在 chunked 分帧下 O(n²) 的性能问题: 维持 ChunkedDecoder 跨调用,仅处理新增字节,总复杂度 O(n)。

§用法

let mut parser = ResponseParser::new();
loop {
    // 读取数据追加到 buf...
    match parser.feed(&buf)? {
        Some((resp, consumed)) => { /* 完整响应 */ break; }
        None => { /* 等待更多数据 */ }
    }
}

Implementations§

Source§

impl ResponseParser

Source

pub fn new() -> Self

创建解析器

Source

pub fn feed( &mut self, buf: &[u8], ) -> Result<Option<(ClientResponse, usize)>, ClientError>

增量解析:输入当前全量缓冲,返回已完成的响应或等待更多数据

parse_response API 兼容:返回 Ok(Some((resp, consumed))) 表示 完整响应已就绪(consumed 为从头开始的消费字节数),Ok(None) 表示 等待更多数据。
