Implementations§

impl Options

source

pub const fn new() -> Options

Create options with default values.

source

pub const fn is_valid(&self) -> bool

Check if the options state is valid.

source

pub const fn lossy(&self) -> bool

Get if we disable the use of arbitrary-precision arithmetic.

source

pub const fn exponent(&self) -> u8

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

source

pub const fn decimal_point(&self) -> u8

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

source

pub const fn nan_string(&self) -> Option<&'static [u8]>

Get the string representation for NaN.

source

pub const fn inf_string(&self) -> Option<&'static [u8]>

Get the short string representation for Infinity.

source

pub const fn infinity_string(&self) -> Option<&'static [u8]>

Get the long string representation for Infinity.

source

pub unsafe fn set_lossy(&mut self, lossy: bool)

Set if we disable the use of arbitrary-precision arithmetic.

§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.

source

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]>)

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

§Safety

Always safe, just marked as unsafe for API compatibility.

source

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

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

§Safety

Always safe, just marked as unsafe for API compatibility.

source

pub const fn builder() -> OptionsBuilder

Get OptionsBuilder as a static function.

source

pub const fn rebuild(&self) -> OptionsBuilder

Create OptionsBuilder using existing values.
