BodyStream

Struct BodyStream 

Source
pub struct BodyStream<'a> { /* private fields */ }
Expand description

Body 流(单消费者,借用语义,零拷贝)

Body 只能被读取一次,消费后标记为已消费。

Implementations§

Source§

impl<'a> BodyStream<'a>

Source

pub fn new(data: &'a [u8]) -> BodyStream<'a>

创建新 Body 流

Source

pub fn get_data(&mut self) -> Option<&'a [u8]>

获取 Body 数据(仅首次调用有效)

§Returns
  • Some(data) - 首次调用返回数据
  • None - 已消费或无数据
Source

pub fn is_consumed(&self) -> bool

检查是否已消费

Source

pub fn len(&self) -> usize

获取 Body 长度(不改变消费状态)

Source

pub fn is_empty(&self) -> bool

Body 是否为空
