Module block_handler

General purpose implementation of block transfer support (RFC 7959).

Supports both Block1 and Block2 and is intended to be compliant with the standard but lenient to tolerate mixed use cases. In-memory caching of request and response bodies is used to achieve the generic interaction.

Structs

BlockHandler

Implements block transfer by intercepting and caching requests and responses.

BlockHandlerConfig

The configuration for BlockHandler.

BlockState

State that is maintained over several requests.

BlockValue

The block option value.

RequestCacheKey

Cache key for uniquely identifying a request.

Functions

extending_splice

Similar to Vec::splice except that the Vec’s length may be extended to support the splice, but only up to an increase of maximum_reserve_len (for security reasons if the data you’re receiving is untrusted ensure this is reasonably limited to avoid memory pressure denial of service attacks).
