Function write_f64

src/encode.rs:606–611

Encodes and attempts to write an `f64` value as a 9-byte sequence into the given write. The first byte becomes the `f64` marker and the others will represent the data itself. # Errors This function will return `ValueWriteError` on any I/O error occurred while writing either the marker or the data, except the EINTR, which is handled internally.

(wr: &mut W, val: f64)

/// This function will return `ValueWriteError` on any I/O error occurred while writing either the
/// marker or the data, except the EINTR, which is handled internally.
pub fn write_f64<W>(wr: &mut W, val: f64) -> Result<(), ValueWriteError>
    where W: Write
{
    try!(write_marker(wr, Marker::F64));
    write_data_f64(wr, val)
}

/// Encodes and attempts to write the most efficient string length implementation to the given
/// write, returning the marker used.
