Struct ryu::Buffer

source · []
pub struct Buffer { /* private fields */ }
Expand description

Safe API for formatting floating point numbers to text.

Example

let mut buffer = ryu::Buffer::new();
let printed = buffer.format_finite(1.234);
assert_eq!(printed, "1.234");

Implementations

This is a cheap operation; you don’t need to worry about reusing buffers for efficiency.

Print a floating point number into this buffer and return a reference to its string representation within the buffer.

Special cases

This function formats NaN as the string “NaN”, positive infinity as “inf”, and negative infinity as “-inf” to match std::fmt.

If your input is known to be finite, you may get better performance by calling the format_finite method instead of format to avoid the checks for special cases.

Print a floating point number into this buffer and return a reference to its string representation within the buffer.

Special cases

This function does not check for NaN or infinity. If the input number is not a finite float, the printed representation will be some correctly formatted but unspecified numerical value.

Please check is_finite yourself before calling this function, or check is_nan and is_infinite and handle those cases yourself.
