Expand description

Extends Write with methods for writing numbers. (For std::io.)

Most of the methods defined here have an unconstrained type parameter that must be explicitly instantiated. Typically, it is instantiated with either the BigEndian or LittleEndian types defined in this crate.

Examples

Write unsigned 16 bit big-endian integers to a Write:

use byteorder::{BigEndian, WriteBytesExt};

let mut wtr = vec![];
wtr.write_u16::<BigEndian>(517).unwrap();
wtr.write_u16::<BigEndian>(768).unwrap();
assert_eq!(wtr, vec![2, 5, 3, 0]);

Provided methods

Writes an unsigned 8 bit integer to the underlying writer.

Note that since this writes a single byte, no byte order conversions are used. It is included for completeness.

Writes a signed 8 bit integer to the underlying writer.

Note that since this writes a single byte, no byte order conversions are used. It is included for completeness.

Writes an unsigned 16 bit integer to the underlying writer.

Writes a signed 16 bit integer to the underlying writer.

Writes an unsigned 32 bit integer to the underlying writer.

Writes a signed 32 bit integer to the underlying writer.

Writes an unsigned 64 bit integer to the underlying writer.

Writes a signed 64 bit integer to the underlying writer.

Writes an unsigned n-bytes integer to the underlying writer.

If the given integer is not representable in the given number of bytes, this method panics. If nbytes > 8, this method panics.

Writes a signed n-bytes integer to the underlying writer.

If the given integer is not representable in the given number of bytes, this method panics. If nbytes > 8, this method panics.

Writes a IEEE754 single-precision (4 bytes) floating point number to the underlying writer.

Writes a IEEE754 double-precision (8 bytes) floating point number to the underlying writer.

Implementors

All types that implement Write get methods defined in WriteBytesExt for free.
