Struct ShardCoverage 

pub struct ShardCoverage {
    pub total: u32,
    pub missing: Vec<u32>,
    pub holes: Vec<(u64, u64)>,
}

分片集合的缺片情况，用于降级播放（规范 §8.4）。

Fields

total: u32

总片数。

missing: Vec<u32>

缺失的片序号。

holes: Vec<(u64, u64)>

缺失区间在原密文中的 (偏移, 长度)，落在这些区间的读取必须失败。

Implementations

impl ShardCoverage

pub fn is_readable(&self, offset: u64, length: u64) -> bool

某个密文区间是否完整可读。
