Implementations

impl OptionsBuilder

source

source

pub const fn get_trim_floats(&self) -> bool

Get if we should trim a trailing ".0" from floats.

source

pub const fn get_exponent(&self) -> u8

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

source

pub const fn get_decimal_point(&self) -> u8

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

source

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

Get the string representation for NaN.

source

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

Get the short string representation for Infinity.

source

pub const fn max_significant_digits(
self,
max_significant_digits: Option<NonZeroUsize>
) -> OptionsBuilder

Set the maximum number of significant digits to write.

source

pub const fn min_significant_digits(
self,
min_significant_digits: Option<NonZeroUsize>
) -> OptionsBuilder

Set the minimum number of significant digits to write.

source

pub const fn positive_exponent_break(
self,
positive_exponent_break: Option<NonZeroI32>
) -> OptionsBuilder

Set the maximum exponent prior to using scientific notation.

source

pub const fn negative_exponent_break(
self,
negative_exponent_break: Option<NonZeroI32>
) -> OptionsBuilder

Set the minimum exponent prior to using scientific notation.

source

pub const fn round_mode(self, round_mode: RoundMode) -> OptionsBuilder

Set the rounding mode for writing digits with precision control.

source

pub const fn trim_floats(self, trim_floats: bool) -> OptionsBuilder

Set if we should trim a trailing ".0" from floats.

source

pub const fn exponent(self, exponent: u8) -> OptionsBuilder

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

source

pub const fn decimal_point(self, decimal_point: u8) -> OptionsBuilder

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

source

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

Set the string representation for NaN.

source

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

Set the string representation for Infinity.

source

pub const fn nan_str_is_valid(&self) -> bool

Determine if nan_str is valid.

source

pub const fn inf_str_is_valid(&self) -> bool

Determine if inf_str is valid.

source

pub const fn is_valid(&self) -> bool

Check if the builder state is valid.

source

pub const unsafe fn build_unchecked(&self) -> Options

Build the Options struct with bounds validation.

Safety

Safe as long as is_valid is true. If nan_string or inf_string are too long, writing special floats may lead to buffer overflows, and therefore severe security vulnerabilities.

source

pub const fn build(&self) -> Result<Options, Error>

Build the Options struct.
