Safety

Always safe, just marked as unsafe for API compatibility.

source

pub unsafe fn set_exponent(&mut self, exponent: u8)

Set the character to designate the exponent component of a float.

Safety

Always safe, but may produce invalid output if the exponent is not a valid ASCII character.

source

pub unsafe fn set_decimal_point(&mut self, decimal_point: u8)

Set the character to separate the integer from the fraction components.

Safety

Always safe, but may produce invalid output if the decimal point is not a valid ASCII character.

pub unsafe fn set_nan_string(&mut self, nan_string: Option<&'static [u8 ]>)

Set the string representation for NaN. Unsafe, use the builder API for option validation.

Safety

Always safe, just marked as unsafe for API compatibility.

source

pub unsafe fn set_inf_string(&mut self, inf_string: Option<&'static [u8 ]>)

&mut self,
infinity_string: Option<&'static [u8 ]>
