pub struct ProtobufDecoder<T> { /* private fields */ }
Expand description

Protobuf 消息解码器,支持粘包处理

Implementations§

Source§

impl<T> ProtobufDecoder<T>
where T: Message + Default,

Source

pub fn new() -> Self

创建新的解码器

Source

pub fn add_data(&mut self, data: &[u8])

向解码器添加数据(处理粘包)

Source

pub fn decode_next(&mut self) -> Result<Option<T>, Box<dyn Error + Send + Sync>>

解码下一个完整的消息

返回 Ok(Some(message)) 如果有足够的数据解码一个完整的消息 返回 Ok(None) 如果数据不足(需要更多数据) 返回 Err 如果解码失败

Source

pub fn has_remaining(&self) -> bool

检查是否还有未处理的数据

Source

pub fn remaining_len(&self) -> usize

获取剩余数据长度

Source

pub fn clear(&mut self)

清空缓冲区
