CanonicalHeader

Struct CanonicalHeader 

Source
pub struct CanonicalHeader {
    pub name: [u8; 64],
    pub name_len: u8,
    pub value: [u8; 256],
    pub value_len: u16,
}
Expand description

规范化请求头(固定容量,Copy 语义)

每个头部条目使用固定容量数组存储,避免堆分配。

Fields§

§name: [u8; 64]

头名称(最大 MAX_HEADER_NAME_LEN 字节)

§name_len: u8

头名称实际长度

§value: [u8; 256]

头值(最大 MAX_HEADER_VALUE_LEN 字节)

§value_len: u16

头值实际长度

Implementations§

Source§

impl CanonicalHeader

Source

pub const fn empty() -> Self

创建空头部

Source

pub fn reset(&mut self)

重置头部(清空内容) 用于对象池复用,避免重新创建对象的开销

Source

pub fn from_bytes(name: &[u8], value: &[u8]) -> Option<Self>

从字节切片创建头部(fail-closed)

§Arguments
  • name - 头名称(必须不超过 MAX_HEADER_NAME_LEN)
  • value - 头值(必须不超过 MAX_HEADER_VALUE_LEN)
§Returns
  • Some(CanonicalHeader) - 创建成功
  • None - 名称或值超长(拒绝静默截断,防止截断后语义被篡改)
Source

pub fn name_str(&self) -> &str

获取名称为字符串切片

Source

pub fn value_str(&self) -> &str

获取值为字符串切片

Source

pub fn is_empty(&self) -> bool

是否为空
