Trait FloatFormat 

Source 
pub trait FloatFormat {
    // Required methods
    fn write_f64(f: &mut impl Write, value: f64) -> Result;
    fn write_f32(f: &mut impl Write, value: f32) -> Result;
}
Expand description

This trait allows customization of how json-streaming formats floating point numbers.

There are many valid string representations of a given number. The number 10.0 can e.g. be represented as 10.0, 10, 1e2, 1.0e2, or 1.0e+2 and many others. There is no technical reason to customize this, it is entirely about human readability.

See the ‘float_format’ example for details.

Required Methods§

Source

fn write_f64(f: &mut impl Write, value: f64) -> Result

Source

fn write_f32(f: &mut impl Write, value: f32) -> Result

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
