Struct qiniu_upload_manager::LimitedDataPartitionProvider

pub struct LimitedDataPartitionProvider<P: ?Sized> { /* private fields */ }

受限的分片大小提供者

基于一个分片大小提供者实例，如果提供的分片大小在限制范围外，则调整到限制范围内。

Implementations

impl<P: DataPartitionProvider> LimitedDataPartitionProvider<P>

pub fn new(base: P, min: u64, max: u64) -> Option<Self>

创建受限的分片大小提供者

如果传入 0 作为 min 或 max 将返回 None。

pub fn new_with_non_zero_threshold(
    base: P,
    min: NonZeroU64,
    max: NonZeroU64
) -> Self

创建受限的分片大小提供者

提供 NonZeroU64 作为分片大小类型。
