Crate ciborium_io

Simple, Low-level I/O traits

This crate provides two simple traits: Read and Write. These traits mimic their counterparts in std::io, but are trimmed for simplicity and can be used in no_std and no_alloc environments. Since this crate contains only traits, inline functions and unit structs, it should be a zero-cost abstraction.

If the std feature is enabled, we provide blanket implementations for all std::io types. If the alloc feature is enabled, we provide implementations for Vec<u8>. In all cases, you get implementations for byte slices. You can, of course, implement the traits for your own types.

Structs

• EndOfFile
  An error indicating there are no more bytes to read
• OutOfSpace
  An error indicating that the output cannot accept more bytes

Traits

• Read
  A trait indicating a type that can read bytes
• Write
  A trait indicating a type that can write bytes
