Struct BoundedStorageProvider 

pub struct BoundedStorageProvider<T>
where
    T: StorageProvider,
{ /* private fields */ }

Creates a BoundedStorageReader with a fixed size.

Implementations

impl<T> BoundedStorageProvider<T>

where T: StorageProvider,

pub fn new(inner: T, buffer_size: NonZeroUsize) -> Self

Creates a new BoundedStorageProvider with the specified fixed buffer size.

Note: If the source has a known content length, the argument provided to buffer_size will be compared with the content length and the smaller of the two sizes will be used. This prevents excess allocations when the source is smaller than the buffer.
