Crate buf_redux

[−] Expand description

A drop-in replacement for std::io::BufReader with more functionality.

Features include:

• More direct control over the buffer. Provides methods to:
  • Access the buffer through an &-reference without performing I/O
  • Force unconditional reads into the buffer
  • Increase the capacity of the buffer
  • Get the number of available bytes as well as the total capacity of the buffer
  • Consume the BufReader without losing data
  • Get inner reader and trimmed buffer with the remaining data
  • Get a Read adapter which empties the buffer and then pulls from the inner reader directly
• More sensible buffering behavior
  • Data is moved down to the beginning of the buffer when appropriate
    • Such as when there is more room at the beginning of the buffer than at the end
  • Exact allocation instead of leaving it up to Vec, which allocates sizes in powers of two
    • Vec's behavior is more efficient for frequent growth, but much too greedy for infrequent growth and custom capacities.
• Drop-in replacement
  • Method names/signatures and implemented traits are unchanged from std::io::BufReader, making replacement as simple as swapping the import of the type.

- use std::io::BufReader;
+ extern crate buf_redux;
+ use buf_redux::BufReader;
