+# LEBE
+Tiny, dead simple, high performance endianness conversions with a generic API.
+This crate purposefully does not have a different method, like `write_u16(my_value)`, for each primitive type. Instead, this uses generic type inference: `write(my_u16)`.
+
+# Purpose
+This crate has exactly two purposes:
+ 1. Simple conversion between slices of primitives and byte arrays without unsafe code
+ 2. Simple and fast conversion from one endianness to the other one
+
+The [byteorder crate](https://github.com/BurntSushi/byteorder) uses ![Lines of Code](https://tokei.rs/b1/github/BurntSushi/byteorder?category=code) for this.
+
+This simplifies reading and writing binary data to files or network streams.
+
+
+# Usage
+
+Write values.
+```rust
+ use lebe::io::WriteEndian;
+ use std::io::Write;
+
+ fn main(){
+ let mut output_bytes: Vec<u8> = Vec::new();
+
+ let numbers: &[i32] = &[ 32, 102, 420, 594 ];
+ output_bytes.write_as_little_endian(numbers.len()).unwrap();
+ output_bytes.write_as_little_endian(numbers).unwrap();
+ }
+```
+
+Read numbers.
+```rust
+ use lebe::io::ReadEndian;
+ use std::io::Read;
+
+ fn main(){
+ let mut input_bytes: &[u8] = &[ 3, 244 ];
+ let number: u16 = input_bytes.read_from_little_endian().unwrap();
+ }
+```
+
+Read slices.
+```rust
+ use lebe::io::ReadEndian;
+ use std::io::Read;
+
+ fn main(){
+ let mut input_bytes: &[u8] = &[ 0, 2, 0, 3, 244, 1, 0, 3, 244, 1 ];
+
+ let len: u16 = input_bytes.read_from_little_endian().unwrap();
+ let mut numbers = vec![ 0.0; len as usize ];
+
+ input_bytes.read_from_little_endian_into(numbers.as_mut_slice()).unwrap();
+ }
+```
+
+Convert slices in-place.
+```rust
+ use lebe::Endian;
+
+ fn main(){
+ let mut numbers: &[i32] = &[ 32, 102, 420, 594 ];
+ numbers.convert_current_to_little_endian();
+ }
+```
+
+
+# Why not use [byteorder](https://crates.io/crates/byteorder)?
+This crate supports batch-writing slices with native speed
+where the os has the matching endianness. Writing slices in `byteorder`
+must be done manually, and may be slower than expected.
+This crate does provide u8 and i8 slice operations for completeness.
+Also, the API of this crate looks simpler.
+
+# Why not use [endianness](https://crates.io/crates/endianness)?
+This crate has no runtime costs, just as `byteorder`.
+
+# Why not use this crate?
+The other crates probably have better documentation.
+
+
+# Fun Facts
+LEBE is made up from 'le' for little endian and 'be' for big endian.
+If you say that word using english pronounciation,
+a german might think you said the german word for 'love'.
