Crate bitcoin_io

Rust-Bitcoin IO Library

The std::io module is not exposed in no-std Rust so building no-std applications which require reading and writing objects via standard traits is not generally possible. Thus, this library exists to export a minmal version of std::io’s traits which we use in rust-bitcoin so that we can support no-std applications.

These traits are not one-for-one drop-ins, but are as close as possible while still implementing std::io’s traits without unnecessary complexity.

Macros

• impl_write
  Because we cannot provide a blanket implementation of std::io::Write for all implementers of this crate’s io::Write trait, we provide this macro instead.

Structs

• Cursor
  Wraps an in memory reader providing the position function.
• Error
  The io crate error type.
• Sink
  A sink to which all writes succeed. See std::io::Sink for more info.
• Take
  Reader adapter which limits the bytes read from an underlying reader.

Enums

• ErrorKind
  A minimal subset of std::io::ErrorKind which is used for Error. Note that, as with std::io, only Self::Interrupted has defined semantics in this crate, all other variants are provided here only to provide higher-fidelity conversions to and from std::io::Error.

Traits

• BufRead
  A trait describing an input stream that uses an internal buffer when reading.
• Read
  A generic trait describing an input stream. See std::io::Read for more info.
• Write
  A generic trait describing an output stream. See std::io::Write for more info.

Functions

• sink
  Returns a sink to which all writes succeed. See std::io::sink for more info.

Type Aliases

• Result
  Result type returned by functions in this crate.
